The dataset contains data related to registered offshore sediment disposal sites around the UK coast and includes volumes of disposed material, dredged areas, calculated levels of contaminants in the disposal material and licence details. Data were collated for the years 2000 to 2020. The Centre for Environment, Fisheries and Aquaculture Science (Cefas) on behalf of Department for environment, food and rural affairs (Defra), report these data for the United Kingdom (England, Scotland, Wales, Northern Ireland),...

Measurements of marine biotoxin concentrations quantified in crab and lobster tissues sampled from North East England around the time of the crustacean mortality event(s) during 2021. Samples were collected from October 2021 to May 2022 to determine if toxins were present in tissues which may have impacted animal health. The following instruments and methods we used to determine the concentrations of chemicals within the samples. Amnesic Shellfish Poisoning (ASP) analysis by liquid chromatography (LC) with...

This data resulted from an opportunistic interception of biofouled marine litter floating off the coast of Cornwall. A colony of goose barnacles (Lepas anatifera) and a neustonic isopod Idotea metallica were found attached to the drifting litter. Both these species are not native to the UK. The interception was used as a case study to model the path of the drifting litter to a probable origin in the Western Atlantic, using the biological traits of...

Biodiversity is known to regulate ecosystem functioning under controlled experimental conditions. However, the ‘real-world’ consequences of biodiversity change remain uncertain, as biodiversity–ecosystem function (BEF) relationships observed in nature may be influenced by other drivers. Attempts to disentangle BEF relationships from the effects of confounding factors have so far focused mainly on primary producers, leaving relatively little known about the impact of changes in consumer diversity despite ecosystems experiencing species extirpations and introductions across trophic levels....

The dataset collected includes assessment output relating to the years from 1905 to 2021 inclusive for annual estimates of the following variables for each stock: the annual recruitment estimate; the stock size (spawning stock biomass); landings (tonnes of fish brought to shore); catches (tonnes of fish caught at sea); fishing pressure (a fishing mortality rate); the target fishing mortality that will achieve maximum sustainable yield in the long term (Fmsy); upper and lower range estimates...

Estimating the demographic parameters of contemporary populations is essential to the success of elasmobranch conservation programmes, and to understanding their recent evolutionary history. For benthic elasmobranchs such as skates, traditional fisheries-independent approaches are often unsuitable as the data may be subject to various sources of bias, whilst low recapture rates can render mark-recapture programmes ineffectual. Close-kin mark-recapture (CKMR), a novel demographic modelling approach based on the genetic identification of close relatives within a sample, represents...

CTD depth profiles from a dataset supporting a baseline assessment of marine water quality around Vanuatu, South Pacific. As part of the Commonwealth Marine Economies Programme, water quality measurements were collected over three years in the coastal waters around the island of Efate, and on one occasion around the island of Tanna. Observations focus on Port Vila (Efate), which is the main urbanised area on the Island. Parameters included are: salinity, temperature, turbidity, light attenuation,...

Environmental DNA (eDNA) has been used in a variety of ecological studies and management applications. The rate at which eDNA decays has been widely studied but at present it is difficult to disentangle study-specific effects from factors that universally affect eDNA degradation. To address this, a systematic review and meta-analysis was conducted on aquatic eDNA studies. Analysis revealed eDNA decayed faster at higher temperatures and in marine environments (as opposed to freshwater). DNA type (mitochondrial...

North Sea cod and plaice tagging data with information about fish location, maturation, sea surface temperature (SST), length, weight and time of tagging, recapture. This data can be used to calculate the changes in cod or plaice fertility due to changes in temperature. This data set was generated for delivery on the EU H2020 Pandora project. Between 1961 and 2015, a total of 22,573 cod were tagged and released using either conventional marker-ID tags. From...
