    The data were collected by the IBSS staff at 18 stations in the Black Sea during August 1957 (Cruise 2). This dataset contains abundance data (individuals per liter) for phytoplankton taxa. No additional metadata is available.

    Data collected on the species composition, abundance and biomass, environmental parameters (T&S, dissolved oxygen and nutrients as well as bottom sediments composition and its structural compounds) regarding spatial and temporal localization.

    Zooplankton time-series from the time-series monitoring programme RADIALES, done by IEO at different stations in the Northwest and North Iberian Shelf.

    Since 1994, Ceredigion County Council and a network of shore-based volunteer observes have monitored levels of boat traffic and the occurrence of bottlenose dolphins at seven sites on the coast of Cardigan Bay, Wales. We report high rates of site use and site occupancy by this species during the summer. Although trends in site use may not reflect population trends in the wider region, these data were consistent with recent abundance estimates that indicate that the number of bottlenose dolphins using Cardigan Bay is stable or slightly increasing. Cardigan Bay is a Special Area of Conservation for bottlenose dolphins and other species and habitats. Recreational boating is known to have the potential to cause disturbance to cetaceans and this monitoring study provides data that underpins the effectiveness of management.

    Phytoplankton data collected in the Black Sea, Bosphorus area, Marmara Sea, Aegean Sea, Ionian Sea, Tunisian Strain, and Mediterranean Sea during 65 cruise of the R/V "Kovalevskiy" and processed by Lyudmila Georgieva. <br> The samples were taken with 6 liter bathometers at standard depths and in the thermocline layer. The standard sedimentation technique for samples preparation (Usachev, 1926) was used. Samples were preserved by buffered formalin 40% and were settled within 30 days. Then a volume of water was siphoned off and samples were concentrated to 10-20 ml. After thorough mixing the subsamples (0.05 or 0.1 ml) were transferred to the counting chamber. Organisms were counted in two subsamples at ×300 - 400 magnification.

    Surveys from seven different vessels were merged. Each vessel contained two sightings platforms running concurrently – primary and tracker. This dataset includes sightings from the tracker platform. Sightings from the primary platform are registered in <a href='/dataset/1150' target='_blank'>SCANS II cetacean sightings on primary platform of vessel surveys 2005</a>. Effort or vessel tracks for these surveys are provided with the primary platform dataset. Survey conditions such as sea state, glare, swell, wind are found in the effort data. In the tracker platform, Big-eye binoculars were used. The trackers used to track groups of animals as they came passed the boat and record them accordingly. However, this dataset does not contain such duplicates.

    Monthly time series of phytoplankton species abundance at several depths of the water column in a fixed oceanographic station off Vigo (NW Spain).

    The European Union (EU) Habitats Directive requires Member States to monitor and maintain at favourable conservation status those species identified to be in need of protection, including all cetaceans. In July 2005 we surveyed the entire EU Atlantic continental shelf to generate robust estimates of abundance for harbour porpoise and other cetacean species. The survey used line transect sampling methods and purpose built data collection equipment designed to minimise bias in estimates of abundance.

    A project of NOAA Kai Submon UNCW. This project is aimed to investigate the impacts of turtles' interactions with longline fishing gear with respect to their stress levels, biochemistry, and post-release movements and survivorship. We had the opportunity to capture turtles that had been free-swimming as well as caught in longline fishing gear.
