Water column physico-chemical profiles of lakes and fiords along the northern coastline of Ellesmere Island

Long-term monitoring of the water column properties of lakes and fiords along the northern coastline of Ellesmere Island provides information about the effects of climate change on the vertical structure of these aquatic ecosystems. This dataset spans from 1954 until 2022. It has been compiled as a contribution by the program NEIGE (Northern Ellesmere Island in the Global Environment) from profiling measurements by NEIGE researchers and from published and unpublished records from other researchers working in the area. The provenance of each data series is given in the profiles list. Data was collected when it was logistically possible to get to the study sites during spring or summer.

The dataset includes physico-chemical profiling records from 15 aquatic ecosystems. Measured parameters (temperature, conductivity, salinity, total dissolved solids, pH, oxidation reduction potential, dissolved oxygen, light) varied according to the instruments used (mainly
RBR XR-420-CTD,
RBR XR-620-CTD,
RBR Concerto,
Hydrolab Surveyor 3,
Hydrolab DS5X,
YSI 600QS Quick Sample,
Li-COR LI-192

). Ice cover thickness and snow thickness on the ice cover are also included for each profile.

Profiles for each lake or fiord are presented chronologically and for each instrument used: 1) RBR or historic profiling method, 2) Hydrolab or YSI, 3) LI-COR.
