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...

Throughout the year, at weekly intervals, temperature data were recorded and water samples taken...

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...

Salmon production model

Keith Jeffery
The bio-economic model can be used to identify and summarise potential production scenarios for Atlantic Salmon. Users can specify an initial fish weight, time of year and desired harvest weight; the model would then return the Time to Harvest for this scenario. Furthermore the model can optimise the time spent in an intermediate system such that the time in net pens is reduced below (eg) 12 months. The model is one of the key outputs...
