Description: This data set includes temperature and salinity measurements from 2019 and 2020 in the fjords Ameralik and Godthåbsfjord in southwest Greenland. Seasonal measurements were made at 12 standard stations in Ameralik spaced between 3 and 13 km from one another (AM1-12) in May, July and September 2019. Longer term fjord sampling was also carried out at monthly intervals from March to December 2019 at selected stations (AM3, AM5, AM7, AM10, AM11 and AM12) and March 2020 at station AM5. There was no sea-ice present in Ameralik during sampling. Additionally, sampling was conducted at 13 standard stations in Godthåbsfjord (GF1-13) in May, July and September 2019. In May and July, sea-ice in the inner part of the fjord prevented sampling further in-fjord. Favourable ice conditions during the September campaign allowed the sampling of 4 further standard stations (GF14-17). Longer term fjord sampling in Godthåbsfjord was also carried out at monthly intervals from February to December 2019 at selected stations from GF5 and inwards. All sampling took place on research vessels operating in daytime: the Greenland RV Sanna (May cruise), the commercial Greenland vessels Polar Dive (July cruise) and Tulu (September cruise), and the Greenland Avataq (remaining monthly day trips). At every station depth profiles of conductivity, temperature and pressure were collected using a SeaBird SBE19plus CTD and averaged over 1 m vertical depth intervals. Sensors were calibrated annually by the manufacturer and salinity precision was typically within the range of 0.005-0.010. Temperature (ITS-90) and practical salinity is used. The data have been used to describe the seasonal hydrography of Ameralik, impacted by a land-terminating glacier only, and to compare Ameralik with Godthåbsfjord, which receives meltwater from both land- and marine-terminating fjords.

Description: This data set includes measurements from a weather station in the fjord Ameralik in southwest Greenland from 2019-01-01 to 2019-12-31. Air temperature, photosynthetically active radiation (PAR), wind speed, and wind direction were measured with 10 minute resolution using an Onset weather station located in the inner part of the fjord (64°13.42'N, 50°18.12'W). The data have been used to compliment a description of the seasonal hydrography of Ameralik.

Description: This data set includes temperature and salinity measurements from 2019 and 2020 in the fjord Ameralik in southwest Greenland. There was a SBE microcat (SBE 37-SMP, SeaBird) moored at a depth of ∼6 m located in the inner part of Ameralik measuring water temperature, salinity and pressure with 10 minute resolution. Sensors were calibrated annually by the manufacturer and salinity precision was typically within the range of 0.005-0.010. Temperature (ITS-90) and practical salinity is used. The data have been used to describe the seasonal hydrography of Ameralik, impacted by a land-terminating glacier only, and to compare Ameralik with Godthåbsfjord, which receives meltwater from both land- and marine-terminating fjords.

Description: The NEG2017 cruise took place from 23 August 2017 to 11 September 2017 was part of the Strategic Environmental program for Northeast Greenland with as its goal to provide environmental impact information pertaining to potential oil exploitation and oil spill response activities in the region. The cruise leader for NEG2017 was Eva Friis Møller.

Description: This hydrographic data set includes CTD and XCTD data from the long-term Hydrographic Fjord Program in Godthåbsfjord, Greenland, collected by Greenland Climate Research Centre, Greenland Institute of Natural Resources (GINR), Nuuk, Greenland. XCTDs were deployed from a helicopter close to a marine terminating outlet glacier. The CTDs in Godthåbsfjord were occupied at the edge of a dense ice field during small boat (Avataq) day trips to the inner part of the fjord. The CTDs outside Godthåbsfjord were obtained by RV Sanna and HDMS EJNAR MIKKELSEN in connection with GINR's annual monitoring program.
