Virus shedding and food consumption in KHV challenged carp

Nicola McPherson
This dataset details feeding behaviour and mucus virus titres of 20 carp (Cyprinus carpio) challenged with Koi Herpes Virus (KHV). Twenty carp (E1-E20) were bath challenged with KHV for four hours at 23 degrees Celsius. Five control carp (CA-CE) were mock challenged under the same conditions. KHV challenged and control fish were maintained in separate locations but under the same conditions. Fish were fed up to 40 food pellets daily and the number of uneaten...

Georeferenced data of oil and gas platforms in the North Sea: 2011-2012

Nicola McPherson
Gridded data, in ascii text format, of oil and gas platforms at the spatial extent of the North Sea (2012). Data are produced at three different spatial resolutions: 0.1, 0.25 and 0.5 decimal degree, respectively. Values represent estimated proportion of grid cell occupied by structures. Data were processed and aggregated from the fixed platform database (http://oilandgasuk.co.uk, October 2012) to support projects under the INSITE (INfluence of man-made Structures In The Ecosystem) programme.

Molecular characterization of an Endozoicomonas-like species associated with mass mortalities of king scallop Pecten maximus L. in United Kingdom

Irene Cano
The king scallop Pecten maximus L. is the fastest growing fishery in the UK and currently the second most valuable. Mass mortality events in scallops have been reported associated with rickettsia-like organisms (RLOs) world-wide, however the causative agents were uncharacterised. In May 2013 and 2014 two mass mortality events affecting king scallops were recorded in the Lyme Bay Marine Protected Area (MPA) South West England. Histopathological examination showed gill epithelial tissue infected with RLO at...

Experimental results of trials to assess non-native fish impacts on the diet and trophic position of native pond fishes using stable isotope analysis in outdoor artificial ponds

Tea Basic
These data derive from experiments carried out during the spring and summer months of two successive years (2014 and 2015) in outdoor experimental ponds previously situated in East Sussex. The aim of the experiments was to determine whether or not introduced non-native fish species have an adverse impact on the diet and trophic position of native pond fishes. The experimental set up was more or less identical in both years, the study species in 2014...

SmartBuoy observational network - North Dogger

Naomi Greenwood
On the SmartBuoy, surface measurements of plant nutrient concentrations are derived from two instruments. The NAS-3X in-situ nutrient analyser takes hourly measurements of nitrate concentration, while lower frequency (daily) measurements of nitrate and silicate concentration are derived from laboratory analysis of water samples collected and preserved by the WMS-2 water sampler. An estimate of phytoplankton concentration (biomass) is obtained twice per hour using a fluorometer measuring chlorophyll fluorescence. To aid interpretation of these data, SmartBuoy...
