Cruise Inventory Information

Long name	RV Cefas Endeavour (74E9) cruise 07/12
Short name	07/12
Objectives and Narrative	Objectives 1. To carry out the second year of a preliminary survey of the Botney Gut Silver Pit grounds, 54o 20' - 53o 40' N and 1o 20' - 3 o 15' E, to evaluate Nephrops abundance and define the edges of Nephrops distribution on the ground. 2. To characterise the benthic community. A 2 m beam and/or 3 m beam trawl will be used in some stations, to identify the occurrence of other burrowing species and determine the Nephrops length frequency distribution on this ground. 3. To characterise sediment features at and between TV survey stations using swathe bathymetry. 4. If time allows, burrow occupancy experiments will be carried out by using a zapper sledge, which discharges electric pulses into the sea bottom. 5. To collect juvenile Nephrops hepatopancreas from beam trawl tows to send to the Weymouth CEFAS laboratory (contact: Kelly Bateman). This will be used to conduct a small scale study of juvenile Nephrops norvegicus to see if the disease profile in juvenile differs from that of adults. In particular the lab in Weymouth is looking for an intranuclear bacilliform virus (IBV) which is known to infect other juvenile crustacean species such as Cancer pagurus. After the survey the hepatopancreas will be sampled from juvenile Nephrops norvegicus for histology and electron microscopy. 6. To collect water samples for analysis of phytoplankton communities. Aim 1: water from the vessel's continuous supply will be analysed via flow cytometry. Samples will be filtered to provide pigment and DNA data. Sub-samples will be concentrated and preserved in order to undergo DNA staining and further flow cytometric analysis. This will provide data which can be related to the carbon content of cells. Aim 2: Calibration of the Turner Phytoflash instrument on the Ferrybox system of Endeavour. Water samples will be collected and used to compare variable fluorescence measurements from the Phytoflash system installed permanently in the Ferrybox against independent results from a Chelsea Instruments Fastracka-II.
