Hydrographic and bio-optical data collected from Ryder Bay, West Antarctic Peninsula, in January 2025
GB/NERC/BAS/PDC/02012
Abstract:
This data release includes sensor data collected from Conductivity Temperature Depth (CTD) casts during a field campaign to Ryder Bay in January 2025 as part of the NERC funded SiCLING project (Silicon Cycling in Glaciated Environments), led by Dr K. Hendry from the British Antarctic Survey. Four CTD casts were carried out within the Bay. This research aims to investigate the release of biologically important nutrients and trace elements from glacial sediments in polar coastal environments, and the biogeochemical impact of ongoing glacier retreat.
Funding:
NERC Pushing the Frontiers grant SiCLING (NE/X014819/1).

| Lineage/Methodology: | A total of 4 successful CTD casts were undertaken using an RBR Concerto and additional sensors for chlorophyll fluorescence and turbidity. The CTD was lowered in a continuous movement, but rate of recovery likely varied, especially with the hand-winching system. An initial soak of 3 minutes at 5m water depth was carried out, before winching the frame to the surface and lowering to within approximately 200m water depth. Between casts the CTD frame and sensors were washed in freshwater. The data were downloaded and processed using RBR software and MATLAB. |
