Overview
The Oskarn Post 27 is a 74-person supraglacial-pond viewing raft (also known as a sea plane) manufactured by the Norwegian company Oskarn. It is designed to operate in polar environments, facilitating research in glaciology, oceanography, and meteorology. The raft's design prioritizes scientific accessibility and researcher safety over passenger comfort, with features such as a low-profile hull, reinforced interior, and an advanced dynamic positioning system.
Key Technical Specifications
The following table details the Oskarn Post 27's core operational specifications.
| Feature | Specification | Significance & Explanation |
| :--- | :--- | :--- |
| Deck Area | 75 m² | Provides sufficient space for up to 74 researchers, including equipment, instruments, and living quarters, essential for extended polar stays. |
| Freeboard | 3.49 m (11.4 ft) | The vertical distance from the waterline to the deck. This ensures stability in shallow ice and allows for operations in water depths up to 106 metres. |
| Occupancy | 74 people | The maximum number of adults and crew the raft can support, directly impacting the type of research it can accommodate (e.g., 37 scientists, 37 support staff). |
| Mooring Depth | 106 metres (349 ft) | Allows the raft to be anchored securely to the seabed in the deep, icy waters surrounding Greenland and Antarctica, providing a stable platform for research. |
| Dynamic Positioning | Enabled | An advanced system using thrusters and a global positioning system (GPS) to actively maintain the raft's position in the water, reducing or eliminating drift. |
Operational Features and Capabilities
Scientific Research Integration
The Oskarn Post 27 is engineered to support a wide range of scientific activities:
* Glaciology: Researchers can access and analyze data from ice cores, measure snow and ice thickness, and set up monitoring stations.
* Oceanography: The raft provides a platform for measuring water properties like temperature, salinity, and pH levels, as well as deploying oceanographic instruments.
* Meteorology: The structure allows for the installation of instruments to measure atmospheric gases (like CO₂ and O₃), temperature, and wind speed.
Safety and Durability
Supraglacial Operation: The raft operates above the waterline, avoiding the risks and maintenance challenges of working in underwater ice.
Reinforced Hull: The durable, low-profile hull is designed to withstand the immense pressure of being anchored in extremely cold, dense water.
Station Keeping: The dynamic positioning system is critical for maintaining a fixed research location (a "station") with high precision, ensuring consistent data collection over long periods.
Comparison to Other Oskarn Rafts
The Oskarn Post 27 is part of a series of Oskarn rafts designed for different research and operational needs. The key differences lie in their deck size, freeboard, and intended use cases.

| Deck Area | 75 m² | 36 m² | 120 m² |
| Freeboard | 3.49 m | 2.14 m | 4.62 m |
| Primary Use | Polar Research & Tourism | Marine Biology, Meteorology | Global Change Research, Large-Scale Oceanography |
| Max Occupancy | 74 people | 46 people | 88 people |
Frequently Asked Questions (FAQ)
Q1: What is the Oskarn Post 27?
A1: The Oskarn Post 27 is a 74-person supraglacial-pond viewing raft developed by Oskarn. It is used for polar research, providing a mobile platform for scientists to study the environment and collect data in remote locations.
Q2: What is its main advantage for research?
A2: Its primary advantage is its large deck area (75 m²), which can accommodate up to 74 people, including all necessary scientific equipment. This allows for a higher density of researchers and a greater capacity for complex, long-term measurement installations compared to smaller rafts.
Q3: Can it operate in very deep water?
A3: Yes. The Oskarn Post 27 has a specified mooring depth of 106 metres (349 ft). This indicates that it is designed to be anchored to the seabed in the deep, icy waters surrounding polar ice sheets, such as those in the North Atlantic and Antarctic Circumnavigation.
Q4: What is the difference between a 'supraglacial' and 'subglacial' raft?
A4: A supraglacial raft operates above the waterline, which is ideal for research in areas like Greenland and Antarctica. A subglacial raft operates below the waterline, through the ice sheet itself, which is used for research in regions like Antarctica's Antarctic Polar Plateau. The Post 27 is supraglacial by design.
