Descrição

The community composition of suspended protists was investigated at 3 stations on the East Greenland continental shelf as part of the EU project ECOTIP. Water was sampled with a 1.7 L Nansen Water bottle at the stations LCC1 (13 May 2022), LCC2 (14 May 2022), and LCC3 (17 May 2022) at 5, 15, 35 m. At station LCC2, a sample was also collected at 90 m. Water samples were collected through a hole in the land-fast sea ice at station LCC1 and LCC2 and from a ship at station LCC3 (station located in a polynya outside Scoresby Sound). The collected water was gently transferred into a carboy, which was stored cool (not freezing) and in darkness until handling within few hours. From each carboy, a subsample of 100 mL was transferred into a glass bottle, preserved with 1 mL acidic Lugol’s solution for later microscopic analysis. The CTD data from the stations and the suspended concentration of chlorophyll a (> 0.7 micrometer and > 10 micrometer) as well as the organic carbon and nitrogen can be found in the NIRD research data archive (https://doi.org/10.11582/2023.00046 and https://doi.org/10.11582/2024.00037).

Dados Sobre o Projeto

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.

Métodos de Amostragem

At each station, the water was gently transferred from the 1.7 L Nansen water bottle to a carboy (using a silicon hose). The carboy was stored cool and in darkness until handling aboard the ship Le Commandant Charcot. There, a subsample of 100 mL was transferred from the carboy to a glass bottle and preserved with 1 mL acidic Lugol’s solution. The sample was stored cool (+4 C) and in darkness until further analysis ashore.

Área de Estudo At 3 sampling stations (LCC1, LCC2, LCC3) on the East Greenland continental shelf, water was collected in repeated casts of a Nansen water bottle at 5, 15, and 35 m. In addition, water was collected at 90 m at station LCC2. While the water was collected through a hole in the land-fast sea ice at station LCC1 and LCC2, the water was collected at LCC3 from a ship (located in a polynya outside Scoresby Sound).

Descrição dos passos do método:

  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.
