Show Abstract
Under the Developing Arctic Modeling and Observing Capabilities for Long-term
Environmental Studies (DAMOCLES) project, an acoustic Doppler current profiler
(ADCP) was deployed at the sill separating the Storfjorden in Svalbard
Archipelago and Storfjordrenna north of Storfjordbanken on the Barents Sea
shelf. Storfjorden, through its polynya activity, produces highly saline water
near the freezing temperature which fills the fjord to the sill level (115 m)
and initiates a gravity driven overflow. A self-contained 307.2 KHz broadband
Workhorse, Sentinel, RD Instruments ADCP was deployed at 76deg 58min N, 19deg
15min E at the 111 m isobath on 17 december 2004. The instrument was recovered
on 12 August 2005. The instrument is installed in an aluminum trawl-proof frame,
attached to a concrete block of 2.5x2.5x0.37 m dimensions. The ADCP sampled at
4-m depth cell size, averaging data (33 pings per ensemble) at 10 min intervals.
The first cell was centered at about 6 meter above seafloor. This dataset
consists of hourly averaged vertical profiles of current velocities as well as
temperature at the instrument depth.
