These data address the interaction of the ocean with tidewater glaciers around the margins of the Greenland Ice Sheet is thought to be a key control on ice sheet stability. Thus, understanding the processes which drive melting of the calving fronts of tidewater glaciers by the ocean is fundamental to projections of future global mean sea level rise. Our understanding is however currently limited, partly due to the scarcity of oceanographic data from close to the calving fronts of tidewater glaciers. The primary goal of these measurements was to quantify the ocean conditions adjacent to a west Greenland tidewater glacier. In particular, knowledge of the water temperature and water velocity is highly valuable as these are understood to be the two primary variables determining the rate at which the ocean melts the calving front of the glacier. These temperature, salinity, and velocity data were collected near a tidewater glacier in Sarqardleq Fjord, West Greenland during July 2012. Data are in NetCDF. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

NOAA National Centers for Environmental Information custodian ADCP ADCP Acoustic Doppler Current Profiler The Acoustic Doppler Current Profiler (ADCP) measures currents beneath a ship while underway. Sound signals sent from the moving ship bounce back to receivers aboard the ship. This provides a profile of water movement relative to the ship-precise modern navigation, allowing the ship's motion to be subtracted from the data. These devices are also used on moorings and profilers and, along with acoustic backscattering, measure animal biomass. Particles in the path of the sound waves, mostly plankton, reflect a small part of the sound energy back toward receivers, allowing researchers to make remote estimates of the sizes and numbers of animals present in the water column. Before the 1970's, the most technologically advanced instrument used to measure water velocity was known as a Doppler speed log. This evolved into the first commercial ADCP, produced in the mid-1970's, which used averaging. Later in the 1970's, the first vessel-mounted ADCP was developed to measure water velocity more accurately and to allow measurement in range cells over a depth profile. As instruments evolved, so did new techniques in Doppler signal processing. Initially, Doppler speed logs used simple analog signal processing methods, which are still used in some commercial speed logs today. However, the first ADCPs incorporated analog-to-digital signal conversion over a narrow communication bandwidth. Around 1990, this technique was developed into broadband signal processing. Since then, broadband ADCPs have been able to generate very accurate, real-time velocity measurements.
