Conductivity, temperature, depth (CTD) data from Blaso epishelf lake, Northeast Greenland, July-August 2017
Fieldwork was undertaken at the epishelf lake, Blaso, in Northeast Greenland between 19th July and 11th August 2017. CTD casts were made between 27/7/17 and 10/8/17.
The CTD operated continuously and was deployed using a hand-spooled winch from a small boat at eight sites across the lake, with the objective of characterising water conditions at both calving fronts and in the three lake basins identified by the CHIRP survey. The CTDs were sampled between 31st July and 10th August 2017 and during this period there was persistent lake ice which prevented CTD measurements close to the eastern calving front. In contrast, most of the lake ice in the western basin had dispersed and melted by early August, allowing access to the western calving margin. Depth temperature and salinity observations are reported as metres (m), degrees centigrade (Deg C) and Practical Salinity Units (PSU).

Methodology:
CTD profiles were measured with a Valeport MiniCTD rated to 500 m with a pressure-balanced conductivity cell, 50 bar strain gauge pressure sensor, and a Platinum Resistance Thermometer sensor. We used the Datalog X2 software package to record and manipulate CTD data. Manufacturer-cited accuracy was ±0.01 mS/cm, ±0.01 °C, and ±0.05% for pressure. The CTD was factory-calibrated two months before the measurements reported here. The CTD operated continuously and was deployed using a hand-spooled winch from a small boat at eight sites across the lake, with the objective of characterising water conditions at both calving fronts and in the three lake basins identified by the CHIRP survey.
The reported data are from DOWN-casts only and all UP-cast data have been removed due to greater potential to be contaminated by sediment from the lake bed that stuck to the CTD. The instrument was corrected to atmospheric pressure just before each cast (readings in air vary between -2 and 5 cm water depth equivalent). Cast was on a hand line with a hand-spooled winch.

Data quality:
Data have been 'cleaned' to remove recording in air before cast.
