The data included in this dataset were collected in the Sermilik Fjord, located in East Greenland in the Ammassalik district close to the town of Tasiilaq. Data collection was conducted by deploying five moorings from September 2012 to August 2013. One mooring was not recovered. The four recovered moorings were named CM0, CM1, CM5, and SF4. Mooring CM0 was located mid-fjord at a depth of 125 meters and was equipped with an SBE MicroCAT, an RBR DR-1050, and an Onset U-22 ProV2. Mooring CM1 was located next to CM0 at a depth of 125 meters. It was equipped with an SBE MicroCAT, an RBR DR-1050, and an Onset UTBI-001 TidbiT. Mooring CM5 was located outside of the fjord entrance at a depth of 290 meters. It was equipped with an SBE MicroCAT and a Nortek Aquadopp. Mooring SF4 was positioned in the middle of the fjord at a depth of 880 meters. Data collected from this mooring included two RBR XR-420s, ten Onset UTBI-001 Temperature Loggers, two SBE MicroCAT, an RBR DR-1050, a Nortek Aquadopp, and an RDI LR-ADCP.
This dataset is available to the public for a wide variety of uses including scientific research and analysis.

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.

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.
