Nematode abundance of the Eastern Mediterranean Sea in cold seep sediments collected during Maria S. Merain cruises MSM13/3 and MSM13/4 in 2009

Sediment was collected by either push cores operated by the ROV Quest or by a television guided Multicorer. Nematodes abundance were calculated of the top 5 cm of the sediment to gain individual abundance per 10 cm**2.

Nematode abundance of the Eastern Mediterranean Sea in cold seep sediments collected during the MEDECO2 cruise (2007)

Sediment was collected by either push cores operated by the ROV Quest or by a television guided Multicorer. Nematodes abundance were calculated of the top 5 cm of the sediment to gain individual abundance per 10 cm**2.

Abundance of microplankton in the eastern Mediterranean Sea in April 2008 during SES_GR2

The dataset is based on samples taken from 12 stations in Northern Aegean Sea, Southern Aegean Sea, Ionian Sea and Libyan Sea during August-September 2008. 12 Niskin bottles (8lt) made by PVC with rubber coated o rings and stainless steel ss springs. Seawater samples (150 mL) were collected from selected depths of the water column (2, 20, 50, 75, 100 m) for the identification and enumeration of phytoplankton cells (>= 5 µm). The samples were fixed with Lugol solution and concentrated to 25 mL by sedimentation. Phytoplankton species abundance was determined with an inverted light microscope (OLYMPUS IX70) according to the Utermohl method (Utermohl, 1958).
