If the recent global warming trend observed on the Antarctic Peninsula persists over the long term, increasing aridity is expected, due to the loss of glaciers. However, the molecular mechanisms of Antarctic moss that allow survival in this harsh and dynamic region have yet to be investigated. Thus, we assembled a draft genome of Sanionia uncinata. A high-quality genome assembly of Sanionia uncinata will facilitate genomic, transcriptomic, and metabolomic analyses of the quality traits that make the moss species one of the world’s strongest plant.
Physical and chemical dataset obtained in the northern Chukchi Sea during the ARA06B (2015), ARA07B (2016), and ARA08B (2017) cruises.
The data includes the hourly GPS locations and 2-hourly surface temperatures of the drifting sea ice floe where the Arctic sea ice camp was carried out in 2016 (ARA07B), which was obtained by the sea ice mass balance buoy deployed on 15 August. Originally the buoy measured the 5-m depth vertical temperature profile at 2.5 cm intervals from near-surface air to upper-ocean underneath sea ice. From the temperature profile, the surface temperature was retrieved by picking up the two neighboring thermistor chips just below the air-snow/ice interface and averaging them. The period is limited from the deployment to 19 August when the IBRV Araon sailed the Chukchi Sea.
Araon is an ice-breaker research vessel for scientific research in Arctic and Southern Oceans. This is one of data collected by DaDiS, the primary data management system for conducting research and observations at Araon.
Warming the Arctic surface ocean due to influx of warm Pacific water not only leads to the declining of the sea ice extent but also triggers melting gas hydrate stored in the Arctic Sea floor of the continental shelf areas. Methane (CH4) is the most abundant hydrocarbon in the atmosphere, where it plays a much more effective role as the greenhouse gas than carbon dioxide (CO2). To understand the behavior of gas hydrate in the sediment and to estimate the CH4 fluxes from the sediment through the water column to the atmosphere, we obtained data on water temperature, salinity, density and fluorescence in the water column.
