Air samples were collected at the Rothera Time-Series (RaTS) site, Marguerite Bay, during the 2008-2009 field season. These were collected in addition to the surface water samples, in order to allow for the calculation of the direction and rate of flux of the bromocarbons across the sea-to-air interface.
Time-series data of bromocarbon compound concentrations - bromoform (CHBr3) and dibromomethane (CH2Br2) concentrations. These were collected at the Rothera Time-Series (RaTS) site, Marguerite Bay during the 2008-2009 field season.
Samples of seawater were collected from the upper watercolumn at the RaTS site and examined to assess bromocarbon production by different microalgal species and how this production varies with changing environmental conditions. The field report (see reference) supplies dates on which the samples were collected and the incubations were started, and the depths incubated.
Water samples were collected from Ryder Bay at the Rothera Time-Series (RaTS) site, using a small boat. A biogeochemical profile was performed at the following 5 depths: 0m (surface), 5m, 10m, 15m and 25m, for four RaTS events on: 7 January, 13 January, 19 January and 1 February 2005. Samples were taken for: phytoplankton nitrate, ammonium and urea uptake measurements, using stable isotope incubations and also primary production PvE curves were produced using 14C radioisotope incubations; Dissolved macronutrients (nitrate, silicate, phosphate, and urea); Surface dissolved iron. A scaled-down sampling RaTS event was performed by the Rothera Marine Assistants involving sampling for all above measurements once every 3 weeks at the 5m depth only at the RaTS site.
