[RESEARCH]
In 2022, even before the construction of permanent infrastructure began, scientific work was already underway — including field research, diving surveys, specimen collection, mapping, and the first applied research projects.
[RESEARCH PROGRAM]
Aniva’s scientific program is built around the idea of southern Sakhalin as a single interconnected natural system. We begin by establishing a baseline understanding of the region — its biodiversity, hydrology, benthic communities, coastal landscapes, and seasonal dynamics — and gradually transform this knowledge into a foundation for biotechnology, mariculture, predictive models, educational programs, and applied solutions.
At Aniva, fundamental research and practical applications are not seen as opposing directions. Species inventories, current mapping, GIS, underwater imaging, and the study of cold-adapted organisms provide the essential knowledge base for the sustainable use of marine resources, technological development, and the long-term management of marine ecosystems.

BIODIVERSITY INVENTORY OF ANIVA BAY
BIODIVERSITY INVENTORY OF ANIVA BAY
Before searching for new bioactive molecules, planning aquaculture, building predictive models, or making management decisions, we first need to answer a fundamental question: **what lives here?** Which organisms inhabit these waters, what communities do they form, how do they change with the seasons, and how are local ecosystems structured?
For the area around Cape Anastasia and the western part of Aniva Bay, no comprehensive picture yet exists. Available data are fragmented, often separated by decades, and do not provide a systematic understanding of the region. This is why biodiversity inventory is the station’s first fundamental research priority and the foundation for all other areas of work.
Systematic field research began in 2022 and continues through the annual **Krilion expeditions**. We survey terrestrial and coastal habitats, conduct underwater photo and video transects, study benthic communities across different depths and substrate types, and collect aquatic organisms for morphological and molecular analysis. Intertidal and coastal zones are mapped using drones, while plankton communities are studied through net sampling linked to hydrological parameters.
A separate area of research focuses on molecular methods, including metabarcoding and environmental DNA (eDNA) analysis of water and sediment samples. These approaches make it possible to detect organisms that are difficult to identify using conventional methods, including microbial communities and species that are challenging to distinguish morphologically.
Biodiversity inventory has no final endpoint. It is a long-term mission of the station: to continuously accumulate data, track change over time, and gradually build a digital map of life across the region — multilayered, expanding, and constantly updated.

HYDROLOGY AND CURRENT MAPPING OF ANIVA BAY
HYDROLOGY AND CURRENT MAPPING OF ANIVA BAY
Aniva Bay is of major economic and ecological importance, yet detailed, up-to-date maps of its currents, tidal and wind-driven water-level fluctuations, and local hydrodynamics remain limited. For scientific research, mariculture, and marine area management, this is a critical knowledge gap.
We are developing a monitoring system for currents, wave conditions, temperature, salinity, and other hydrophysical parameters. These data are essential not only for a fundamental understanding of the bay, but also for practical applications: selecting sites for seaweed farms, assessing risks, planning diving operations, and predicting the transport of larvae, biomass, or potential pollutants.
In the future, we plan to use these data to develop predictive models of Aniva Bay — a tool that will support more accurate scientific, engineering, and management decisions.

ANIVA GEOGRAPHIC INFORMATION SYSTEM (GIS)
ANIVA GEOGRAPHIC INFORMATION SYSTEM (GIS)
Field data lose much of their value when they are fragmented, disconnected from spatial context, or inaccessible to other researchers. From the outset, we have therefore built the station’s work around a simple principle: every observation should have coordinates, a documented methodology, a description, and a place within a shared data system.
A diving transect, sampling point, hydrological measurement, record of a rare mollusk, habitat description, drone image, or underwater video — all of these should become part of a unified digital database.
The technical foundation of this approach is the Aniva Geographic Information System (GIS) — a comprehensive GIS project being developed in 2026 with support from a grant from the Russian Geographical Society. During the station’s first years of operation, a substantial body of data has been collected on biodiversity, hydrology, botany, marine biology, and underwater imaging, but these materials currently remain dispersed across different formats and archives.
As part of the project, we are developing a methodology for integrating interdisciplinary data, designing the database architecture, and creating a public web geoportal — an open-access tool for the scientific community, partners, and future researchers working at the station.
In the long term, the Aniva GIS is intended to become a **digital twin of the region**: a multilayered map in which water dynamics, seafloor topography, species distribution, routes, sampling points, and long-term monitoring data are connected within a single system. This infrastructure will support predictive modeling, marine spatial planning, assessment of mariculture potential, and the conservation of natural ecosystems.
The methodology being developed at Aniva is designed to be scalable and transferable to other biological stations, protected areas, research institutions, and regional environmental monitoring systems.

SEAWEED
AND MARINE BIOTECHNOLOGY
SEAWEED
AND MARINE BIOTECHNOLOGY
Sakhalin kelp, Saccharina japonica, is one of the region’s most abundant renewable marine resources and, at the same time, a raw material with significant biotechnological potential. Brown algae contain valuable polysaccharides, pigments, and other biologically active compounds, including fucoidan, fucoxanthin, alginates, mannitol, and mineral fractions.
Today, many of these ingredients are either imported into Russia or are not yet produced domestically at an industrial scale. For Sakhalin, the challenge is therefore not only to harvest seaweed, but also to develop a high-value processing chain.
At Aniva, we are developing a cascade processing approach — a model in which several target fractions are extracted sequentially from a single batch of raw material. This approach increases the value derived from each tonne of biomass while reducing waste.
Our key R&D questions focus on how harvest season, growing location, algal age, and primary processing methods affect the concentration of active compounds; how raw material quality varies; which fractions can be produced consistently; and how these profiles can be standardized for industrial applications.
This research area brings together field biology, natural products chemistry, processing technologies, and the development of a future marine bioeconomy for the region.

KELP AND MULTI-TROPHIC AQUACULTURE
KELP AND MULTI-TROPHIC AQUACULTURE
Aniva Bay is one of the most promising areas of Sakhalin for kelp cultivation. Its cold, nutrient-rich waters, high primary productivity, and extensive natural stocks of Saccharina japonica make the bay suitable not only for harvesting wild seaweed, but also for controlled mariculture.
Together with Sakhalin State University and industry partners, we are developing an experimental seaweed and multi-trophic aquaculture farm near Cape Anastasia — from an engineering prototype to a model for sustainable commercial production.
The main engineering challenge is adapting farming systems to the site’s extreme conditions. Storm waves, winter ice loads, and shallow waters make conventional surface-based structures unsuitable. We are therefore developing submerged longline systems with subsurface buoys that can remain below the most active wave zone and beneath the ice cover, keeping the biomass in safer conditions.
The ultimate goal is not simply to create an experimental farm, but to develop a reproducible production model: a stable and controlled source of biomass for advanced processing, with clearly documented origin, seasonality, and bioactive compound profiles. In this way, mariculture becomes directly integrated with the station’s biotechnology program.

PSYCHROPHILIC COMMUNITIES AND BIOACTIVE MOLECULES
PSYCHROPHILIC COMMUNITIES AND BIOACTIVE MOLECULES
The waters around Cape Anastasia and Aniva Bay are shaped by seasonal ice cover, sharp seasonal fluctuations, salinity gradients, and strong tidal and wave dynamics. Summers are warm and humid, while winters are cold and snowy. This combination of environmental conditions creates a natural laboratory for the evolution and selection of rare adaptations.
Under persistent environmental stress, marine organisms, their microbiomes and symbionts, as well as psychrophilic communities, develop distinctive metabolic strategies. Such systems are particularly promising for the discovery of unusual secondary metabolites, cold-adapted enzymes, and compounds with antibacterial, antifouling, or other biological activities.
Our current work focuses on identifying and conducting preliminary analyses of promising microbial communities — those most likely to contain valuable bioactive molecules. Further investigation of the potential of isolated strains will be carried out in collaboration with scientific partners.
This research lies at the intersection of ecology, microbiology, and biotechnology. Metagenomics, metabolomics, and the cultivation of rare strains make it possible to translate fundamental knowledge of biological adaptation into applied developments — from new natural compounds to industrial biocatalysts.

UNDERWATER PHOTO AND VIDEO DOCUMENTATION
UNDERWATER PHOTO AND VIDEO DOCUMENTATION
Underwater imaging at Aniva is not only a way to reveal the beauty of the Sea of Okhotsk and the Sea of Japan. For us, it is a scientific method in its own right — a tool for documenting the condition of benthic communities, animal behavior, species distribution, seasonal changes, and rare observations.
The station works with a team of underwater photographers and filmmakers with experience in international scientific and media projects, including filming for BBC’s Planet Earth III, National Geographic grant-funded projects, and collaborations with Dolby Labs, science museums, and research institutes.
Photo and video documentation serves three purposes at once. For science, it provides data and visual records. For education, it gives students and wider audiences access to the hidden life of the sea. For communication, it offers a way to tell the story of Sakhalin, the Krilion Peninsula, and the biological station in a visual language that reaches far beyond the scientific community.

[RESEARCH INFRASTRUCTURE]
Doing science in the field requires more than ideas and research methods. It requires power, microscopes, refrigeration, reagents, boats, reliable communications, people who know how to work at sea, and the basic living conditions that make it possible to spend not just a day at the station, but an entire field season.
At present, we work as a true field station: some of our laboratories are housed in M-30 military tents and temporary modular structures. Even so, we already have a fully functional field laboratory setup, including a clean area with a biological safety cabinet, incubators, an autoclave, laboratory burners, refrigerators operating at +4 °C and −17 °C, a 35-liter Dewar vessel with liquid nitrogen, basic microscopy equipment, lighting systems, laboratory glassware, and consumables.
This is sufficient for the initial processing and preservation of samples, microscopy, basic microbiological work, and preparation of specimens for further analysis.
By November 2026, the station is expected to have a permanent laboratory building of approximately 200 m², with three equipped spaces: a microbiology laboratory, a teaching laboratory, and a general research laboratory for primary sample processing and routine fieldwork.
For specialized tasks — including molecular biology, high-precision analytical work, biochemistry, and genomics — samples are transferred to partner laboratories at Moscow State University, Sakhalin State University, the Shemyakin–Ovchinnikov Institute of Bioorganic Chemistry of the Russian Academy of Sciences, and other research institutes.
As the station develops, its laboratory infrastructure will continue to expand. The long-term plan includes a main laboratory building of approximately 1,200 m².

The sea is Aniva’s main transport route. People, cargo, fuel, equipment, and nearly everything needed for the station’s work arrive by water. For this reason, maintaining our own fleet is a key part of the station’s infrastructure. The navigation season generally runs from April 15 to November 15, although every trip depends on weather, sea conditions, wind, and the state of the shoreline.
Zvezdochet is the station’s primary transport and support vessel. It is an 11-meter ALEUT LC112 Explorer landing craft equipped with two 250 hp Yamaha engines and custom-built for Aniva Biological Station. The vessel can carry up to 2 tonnes of cargo and up to 10 people, land on an unimproved shore, and is used to transport personnel, equipment, samples, and expedition teams. In good weather, the journey from the settlement of Rybatskoye in the Aniva District to Cape Anastasia takes approximately two hours.
Morzh, a Project SP-20 landing barge, is the station’s main logistics vessel for oversized cargo and heavy equipment. Equipped with a loading ramp, it can unload directly onto an unimproved shore and carry up to 20 tonnes of cargo. The journey from Korsakov to Cape Anastasia takes approximately six hours.
Fregat 550 and SkyLark RIB 500 are small boats used for diving operations, hydroacoustic surveys, side-scan sonar work, echo sounding, and manual sampling. They are also used to transport researchers to remote rivers, isolated sections of coastline, and offshore survey routes.

The station’s diving team consists of experienced divers who are also marine biologists. This combination is essential: underwater, they do more than carry out technical tasks. They understand what to look for, how to collect specimens carefully, how to avoid damaging the subject of study, and how to use limited dive time as efficiently as possible.
The diving team can locate rare marine organisms, collect specimens upon researchers’ requests, conduct underwater photo and video documentation, install and maintain monitoring equipment, perform macro photography, and work with small, fragile, or hard-to-reach specimens.
We provide:

We provide:
- Scientific diving support and a full range of diving operations — planning, organization of dives, safety support, underwater imaging, specimen collection upon request, and installation and maintenance of scientific equipment.
- Diving equipment for visiting researchers — rental of a complete set of diving gear for researchers with the required certifications and authorization to dive.
- Underwater photo and video support — macro, scientific, and creative imaging for research, educational, and media projects.
Around 20 kilometers of coastline can be explored on foot from the station, including intertidal zones, river mouths, rocky shores, an old Japanese road, and forest trails. The Krilion Peninsula is strikingly beautiful, but physically demanding to cross. In many areas, the understory is dominated by dense thickets of Kuril dwarf bamboo (Sasa kurilensis), which makes off-trail travel extremely difficult.
For this reason, most field routes follow the intertidal zone, rivers and streams, or old roads. The station also has ATVs for longer overland journeys, as well as small boats for marine fieldwork and access to remote parts of the peninsula.
On the northern side of the cape lies a broad, accessible intertidal zone, shallow eelgrass beds, and seal haul-out sites. Two small rocky islets rise from the sea in front of the station and are used by seabirds. About 700 meters south of the cape, there is a small waterfall and steep coastal cliffs. These are not only exceptionally beautiful places, but also convenient natural field sites for research.
All field trips are planned according to weather conditions, tides, and shoreline conditions, and are always conducted with station staff or local rangers.

Living conditions at the station are field-based, but provide a comfortable level of essential amenities. Researchers stay in twin rooms; those who prefer a more traditional field experience can also stay in a tent with a camp bed.
The station provides three meals a day, with tea and coffee always available, as well as a common space where researchers can discuss the day’s findings or simply warm up after working at sea.
Water is supplied from the Vodopadnaya River. Its composition has been tested, and the station also operates an additional water treatment system. Electricity is currently provided by diesel generators, with solar panels planned as an additional energy source in the near future. An MTS mobile tower on the station grounds provides cellular coverage and internet access.
The station is located in a remote, wild part of Sakhalin, so safety is an integral part of the infrastructure. The site is protected by bear fencing, and all field trips are planned with weather conditions, tides, and field safety requirements in mind. Aniva is designed to operate year-round, although most field activity takes place during the navigation season. In winter, much of the infrastructure is winterized, while station operations continue on a limited basis.
Important: Aniva is a field station in a remote part of Sakhalin. It provides essential comforts, communications, meals, water, and safety infrastructure, but not the predictability of an urban environment. Weather, the sea, and logistics always remain part of daily life at the station.
