RV Cefas Endeavour 10C/09
Cruise summary report
|Ship name (ship code)||RV Cefas Endeavour (74E9)|
|Cruise period||2009-07-11 — 2009-07-16|
|Port of departure||Portland Harbour, United Kingdom|
|Port of return||Portland Harbour, United Kingdom|
1. To survey dredged material disposal sites at Inner Gabbard, Tees, Souter Point, North Tyne and Rame Head (Plymouth) for benthos, trace metal and organic contaminants in sediments, using grabbing and coring. At a number of sites, various acoustic methods will also be used.
2. To sample representative NMMP locations using grabbing, coring, and trawl methods. Samples will be later analysed for trace metal and organic contaminants, litter and epi-, macro- and meio- fauna.
3. To sample sediments and water at various stations in the Eastern and Western Channel regions for later analysis of macro- and meio- fauna, metals, chlorophyll a, porosity, organic contaminants, nutrients and salinity. This survey forms part of the NMMP redesign program (CSEMP).Narrative
Cefas Endeavour departed Portland at 16:00 11/07/09 and sailed west into Lyme Bay were stations CSEMP 536 (Aim 2) MUSD 1 and MUSD 2 (Aim 3) were sampled for biology, sediment particle size and contaminants. From here Cefas Endeavour transited south collecting CSEMP redesign station 28 E6 (OS) and then west (12/07/09) collecting stations 28 E6 (OS), 28 E5 (OS), 27 E4 (OS), 27 E3 (OS), 27 E2 (OS), 27 E2 (OS), 26 E2 (OS), 26 E1 (OS) (Aim 3) then north (13/07/09) to sample stations 27 E1 (INT) and 28 E1 (OS) (Aim 3). Poor weather conditions during this section of the cruise resulted in the failure to collect some samples due to the grab failing to operate optimally in deep water and rough seas. On completion of station 28 E1 (OS) Cefas Endeavour transited back inshore (14/07/09) to sample the final CSEMP redesign station 29 E5 (INT) (Aim 3) and begin work at the Rame Head dredge disposal site (Aim 1).
Due to the unconfirmed (by the Ministry Of Defence) condition of explosives disposed of at the Rame Head disposal site pre 1983, five stations within the disposal site boundary were abandoned. The decision to drop these stations was taken due to the unacceptable risk of bringing live explosives/ammunition to the surface in the grab or causing an underwater explosion during the deployment of the Hamon grab. On completion of this Hamon and Shipek grab survey, Cefas Endeavour travelled east to collect contaminant samples from CSEMP 575 (Aim 2). Two additional biology, porosity and chlorophyll a samples were collected so data from this station could be included in the CSEMP redesign program (Aim 3). On completion of this station, Cefas Endeavour transited east and docked in Portland 09:00 on 15/07/09.
