Seasonal temperature and salinity measurements from a mooring in Ameralik fjord in 2019

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.

本数据集收录了2019至2020年格陵兰西南部阿默拉利克峡湾（Ameralik）的温度与盐度实测数据。研究团队在该峡湾内湾处布设了一台SBE微猫（SBE 37-SMP, SeaBird）锚定传感器，布设水深约6米，该传感器以10分钟的分辨率同步采集水体温度、盐度与压力数据。传感器每年由厂商进行校准，盐度测量精度通常处于0.005~0.010范围内。本次数据集采用ITS-90国际温标下的温度数据及实用盐度指标。该数据集曾被用于描述仅受陆地终止型冰川影响的阿默拉利克峡湾的季节性水文特征，同时用于对比阿默拉利克峡湾与同时接收陆地及海洋终止型峡湾融水的戈特霍布峡湾（Godthåbsfjord）。
