The community composition of suspended phytoplankton was investigated at 7 stations along the East Greenland coast as part of the EU project ECOTIP. Water was sampled in Dove Bay (1 station: 5, 40, 50 m), Kong Oscar fjord (2 stations: 5, 42, 50 m and 5, 43, 50 m), Arden Caple fjord (3 stations: 5, 40, 50 m; 5, 40, 50 m; 5, 20, 50 m) and outside Scoresby Sound on the continental shelf (1 station: 5, 40, 50 m). While 5 m and 50 m were used as standard depths, the intermediate depth was chosen depending on the fluorescence sub-surface maximum. At each sampling depth, the water was collected with a 10 L Niskin bottle attached to a sampling rosette. A subsample of 100 mL from the Niskin bottle was preserved with 1 mL acidic Lugol’s solution for later microscopic analysis. From this field work, there are also other data available: 1) cruise track with a station list (,, 2) underway measurements (, 3) concentration of suspended chlorophyll a, phaeophytin, particulate organic carbon (POC), and particulate organic nitrogen (PON) (, 4) downward flux of chlorophyll a, phaeophytin, particulate organic carbon (POC), particulate organic nitrogen (PON), and the atomic ratio of POC:PON (, and 5) community composition of sinking protist cells (

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 21 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Project Data

Data were collected as part of the project "Investigating ecosystem tipping points and cascades in the Arctic Seas" (ECOTIP). ECOTIP operates at the important link between the physical and biological systems, where a regional change in the hydrography of the Arctic Ocean might trigger a biological change at the base of the marine food web with cascading effects both on the regional and local socio-economic systems through fisheries, and on the global climate through carbon sequestration. ECOTIP is attempting to anticipate and predict these changes.

Funding This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 869383 .

Sampling Methods

At each station, the water at the three sampling depths was collected using a 10 L Niskin bottle attached to a sampling rosette. The water was gently transferred from the Niskin bottles to carboys (using a silicon hose) and a subsample of 100 mL was preserved with acidic Lugol’s solution (1% final concentration) and the sample was stored cool (+4 C) and in darkness until further analysis ashore.

Study Extent At each of the seven sampling stations in East Greenland (1 station in Dove Bay, 2 stations in Kong Oscar Fjord, 3 stations in Arden Caple fjord, 1 station outside Scroesby Sound), water was collected at 5 m, 50 m, and (close to) the sub-surface fluorescence maximum.

Method step description:

  1. The microscopic analysis was later conducted at the Institute of Oceanology of the Polish Academy of Sciences (IO PAN) in Sopot, Poland and the phytoplankton taxa were identified to the lowest possible taxonomic level.
