Temperature and salinity profiles adjacent to a tidewater glacier in Sarqardleq Fjord, West Greenland, collected during July 2013

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 data are 91 conductivity-temperature-depth (CTD) casts collected near a tidewater glacier in Sarqardleq Fjord, West Greenland. The data were collected during July 2013 and are averaged into 1-m bins.

格陵兰冰盖周边陆缘的海洋与潮汐冰川（tidewater glaciers）的相互作用，被认为是控制冰盖稳定性的核心机制。因此，厘清海洋驱动潮汐冰川冰崩前端消融的物理过程，是预测未来全球平均海平面上升的核心研究基础。但当前学界对该过程的认知仍存在显著局限，部分原因在于潮汐冰川冰崩前端附近的海洋学观测数据极度稀缺。本次观测的首要目标是量化格陵兰西部一处潮汐冰川邻近海域的海洋环境条件。具体而言，水温与水流速度被公认为决定海洋消融冰川冰崩前端速率的两大核心变量，因此获取这两项参数具有极高的科研价值。本次数据集包含2013年7月在格陵兰西部萨尔卡德雷克峡湾（Sarqardleq Fjord）一处潮汐冰川附近采集的91组温盐深（conductivity-temperature-depth, CTD）剖面测量数据，所有数据已按1米间隔完成分层平均处理。
