|Cruise period||2017-01-05 — 2017-01-17|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
1. To collect hydrographic information, including:
- Full depth, conductivity and temperature profiles at each trawl station alongside surface and near-bottom water samples using a Niskin water sampler with ESM2 logger;
- To collect water column alkalinity, dissolved inorganic carbon (DIC), suspended particulate matter (SPM), oxygen and nutrient samples; and
- Continuously logged sub-surface (~3 m depth. salinity, temperature, fluorometry and other environmental data using the ‘Ferrybox’.
2. Collect information on seabed substrata, including:
- Distribution of sedimentary habitats (including biogeochemical parameters; sediment particle size analysis (PSA. and organic carbon (OCN), Porosity/Chlorophyll, O2/pH, Rapid Fines Assessment (RFA. and microplastics);
- Distribution of macrobenthos (infaunal and epifaunal).
3. To collect plankton community and biodiversity data (ichthyoplankton, macro and gelatinous zooplankton).
4. To collect fish, cephalopod and invertebrate community and biodiversity data.
Catches from the trawls (GOV and 2 m beam trawl. will be processed according to International Bottom Trawl Survey (IBTS. protocols as appropriate to obtain information on:
- Distribution, size composition and relative abundance of fish, cephalopods, and epibenthic species;
- Age-length distribution, biological parameters and stomach contents of plaice (Pleuronectes platessa), lemon sole (Microstomus kitt. and haddock (Melanogrammus aeglefinus).
5. Collect information on:
- Distribution and classification of anthropogenic litter/debris and microplastics (according to the protocol provided in Annex 3); and
- Presence and distribution of non-indigenous species (NIS. (according to the protocol provided in Annex 4).
6. To opportunistically record surface sightings of any marine mammals, sea turtles and large pelagic fish and record observations of jellyfish aggregations.
7. To develop and test novel technologies and approaches for monitoring:
- Cefas Automated Litter and Plankton Sampler (CALPS).
