Monthly average non-algal Suspended Particulate Matter concentrations

Tiago Silva
Spatially gridded, monthly average of non-algal Suspended Particulate Matter (SPM). Based on satellite derived Ifremer OC5 algorithm (Gohin et al 2011). Interpolated and merged data from SeaWiFS, MODIS, MERIS and VIIRS satellite sensors. Based on Gohin et al (2005) OC5 algorithm that jointly estimates the load of Chlorophyll and non-algal suspended particulate matter. This algorithm has been validated against in-situ coastal observations for the English Channel and Bay of Biscay (Gohin, 2011) and modified to...

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...

Virus shedding and food consumption in KHV challenged carp

Natural bed disturbance modelling outputs

John Aldridge
This dataset consists of output from a computer model that attempts to predict annual seabed disturbance caused by waves and currents. Disturbance was taken to mean physical movement of the seedbed sediments and was quantified as a disturbance frequency (days per year disturbance occurred). For sandy regions the disturbance depth is also predicted (days per year disturbance occurred to a given depth below the seabed). For gravel and mud substrates the depth of disturbance was...

Georeferenced data of wrecks in the North Sea: 2016
