SHARK - Regional monitoring, recipient control and monitoring projects of phytoplankton in Sweden since 1985

Phytolankton have been regionally monitored in Sweden since 1985.
The monitoring is financed by the Swedish county administration boards, Swedish municipalities and Swedish coalitions of water conservation. Recipient control data financed by companies are also included. Monitoring is performed by Swedish universities and consulting firms.
Data are stored in the Swedish Ocean Archive database (SHARK), by the Swedish Meteorological and Hydrological Institute. Data are collected and analyzed according to the HELCOM COMBINE Manual - Part C Annex C6 Monitoring of phytoplankton species composition, abundance and biomass (https://www.helcom.fi/wp-content/uploads/2019/08/Guidelines-for-monitoring-phytoplankton-species-composition-abundance-and-biomass.pdf) or similar methods.
In short, analysis of phytoplankton species composition, abundance and biomass is carried out for the following purposes - to describe temporal trends in phytoplankton species composition, phytoplankton abundance, biomass as well as the intensity and occurrence of blooms - to describe the spatial distribution of phytoplankton species - to identify key phytoplankton species (e.g. dominating, harmful, potential non-indigenous and/or invasive species, as well as indicator species) - to provide basic data for complex ecosystem analyses, food web studies, modelling as well as political and social requirements such as indicators in the frame of the Marine Strategy Framework Directive of the European Union (MSFD; European Union 2008) and the EU Water Framework Directive (WFD; European Union 2000) (HELCOM COMBINE Manual https://www.helcom.fi/wp-content/uploads/2019/08/Guidelines-for-monitoring-phytoplankton-species-composition-abundance-and-biomass.pdf)

Biological dataset for Pagrus pagrus fished along Southern Brazil

The data were obtained from a regular sampling program of industrial fisheries landings in Rio Grande, southern Brazil. The dataset presented is composed of: Fishing gear with landing date, minimum and  maximum depth of the catches in ech fishing trip.. Individual fish parameters of length, total weight, total, sex, age, maturity stage, gonad weight, gonadosomatic indices and allometric condition factor. Type of the scales border and classification of the readability of the growth rings.
During dock sampling, total length (TL), measured from the tip of the snout to the midpoint of the upper and lower limbs of the caudal fin, was recorded in mm, total weght. (TW) in grams,  and sexed: (1) male, (2) female, (3) undetermined and (4) hermaphrodite. Specimens were classified from macroscopic examination as hermaphrodites when both testicular and ovarian tissues were present in the gonads and as males or females when all or most of the tissue was testicular or ovarian, respectively. Maturity stages were determined macroscopically with a seven-point scale: (1) virginal immature, (2) developing virginal, (3) developing, (4) advanced development, (5) running, (6) partly spent and (7) recovering. Gonads were weighted in grams (GW) and the average gonadosomatic indices were calculated as GSI = 100(GW/TW) . Allometric condition factors (K) were calculated as K = TW/TLb, where b is the coefficient of the weight-length relationship. For age determination, scales collected from behind the pectoral fin insertion. The readability of growth rings on the scales were classified as "well-marked", "faint or absent" and "unreadable". The position of the last ring relative to the posterior border of the scales were classified a (1) recently formed near the border, or  (2) more distant of the border.
Benthic bycatch from dredge surveys for seed mussel (Mytilus edilus) stock assessment, Outer Ards, Northern Ireland

This dataset contains presence/absence information of infaunal bycatch from seed mussel stock (Mytilus edulis) assessment surveys off the Outer Ards Peninsula in Northern Ireland. The seed mussel survey is carried out each year and this particular dataset contains the bycatch information from initial ground truthing (dredge) on these surveys from 2017-02 to 2018- 07.
The dredge samples are taken from the DAERA Fisheries Protection Vessel Queen of Ulster (formally Banríon Uladh). The main aim of the seed mussel survey is to carry out a stock assessment of seed mussel in areas that are fished for these mussels. The stock assessment surveys use acoustic ground discrimination system (AGDS), dredge surveys (ground truthing) and then in areas where there appears to be high levels of seed mussel an underwater video camera sledge is towed from the RV Corystes for more ground truthing. In total there were 42 dredge tows carried out that contained bycatch in this dataset. It is important to note that the information in this dataset was not the key focus of these surveys. The most common species found were Laminaria species. 
"This dataset contains information on the presence and absence of bycaught infauna species during the stock assessment surveys of seed mussel (Mytilus edulis) in the Outer Ards Peninsula in Northern Ireland in 2017 and 2018. As this dataset contains bycatch data it is important to note that the infauna were not the key aim of the survey. The seed mussel stock assessment is carried out with the aim of providing a comprehensive assessment of the state of the seed mussel beds which are commercially fished.  Initially a RoxAnn acoustic ground discrimination system (AGDS) using a 200kHz transducer collected data on the roughness - hardness of the substrate at a save rate of 1s. This acoustic device was deployed off the Fisheries Protection Vessel Queen of Ulster (formally Banríon Uladh). A dredge survey was then carried out from the Queen of Ulster using a custom oyster dredge (1.5m x 0.5m) following the AFBI Standard Operating Procedure (SOP) “Collection - recording of benthic dredge samples”. In total there were 42 dredge tows carried out that contained bycatch in this dataset.The bycaught species were identified as accurately as possible and recorded (presence/ absence).
A towed epibenthic video sledge was used from the RV Corystes to provide further ground truthing information for the stock assessment (this information is not present in this dataset). A Konsberg video camera, halogen lights and point lasers (for scaling) were all attached to the camera sledge and towed at an estimated speed of 0.5-0.8 knots. The footage was reviewed by experienced marine biologists.
ICES Fish stomach contents dataset

The Fish predator/prey database (stomach database) contains data covering 11 countries. A total of 217 399 stomachs are reported in the North Sea data. Eight predator species were analysed and 854 NODC prey codes have been reported
Year of the Stomach content data 
The first year of the stomach ran in 1981 and covered a handful of species in the North Sea. Follow up data collection was performed in 1985-1986, and a decade later in 1991 the 2nd year of the stomach ran. The data were collected as part of an ICES initiative and the results and analysis were presented in two cooperative reports (CRR 164 and CRR 219). 


Geographical Coverage 
There are 2 datasets related to the year of the stomach, North Sea and Baltic respectively. The map to the right shows the distribution of the North Sea records. Currently, only the North Sea dataset is available online. 


About this dataset 
While ICES has made every effort to ensure that the dataset presented here is the most complete set of information, it should be noted that there are a number of versions of this dataset held by institutions and individuals which may differ from this set.
Norfish: Danish Limfjord herring fishery, 1518-1835

NorFish is a European Research Council (ERC) Advanced Grant led by Prof Poul Holm in Trinity College Dublin, focuses on the premise that a 16th century shift in marine fish pricing and supply in conjunction with the Little Ice Age and lowering of sea temperatures not only rise to the North Atlantic Fish Revolution but also forms one of the first documented examples of the disrupting effects of globalisation and climate change. The project examines the role of the Fish Revolution for a range of inter-related aspects of North Atlantic history, with NorFish’s interdisciplinary team drawing on archaeology, history, cartography, geography, and ecology to develop interpretative frameworks that synthesise a broad spectrum of source data to assess the overall objective of the project. NorFish’s interdisciplinary team draws on archaeology, history, cartography, geography, and ecology to assess the objectives of the project.
The Limfjord herring fishery is anomalous due to the unique nature of the changing topography that has forged uniquely inland sea waters in the Jutland Peninsula. Until a breach at Agger Tange in 1825, affording access to the North Sea, the only access was to the east via the Kattegat. The breach enabled salt water to penetrate the Limfjord which had previously been brackish. It may be argued that despite the obvious, radical changes to the salinity, hydrography and nutrient levels that the breach caused, herring fishing was impacted prior to this event by a combination of fishing methods and the destruction of spawning grounds.

Macrobenthos Data from Shoreham, the Tyne and the Thames Estuaries, UK, 2000 to 2006

These data describe counts of macrobenthic infauna (with associated station metadata) taken from sediment samples collected at sites in the Tyne, Thames and Shoreham, UK from 2000 to 2006. For selected samples, wet biomass data is also included per taxon. The samples from the Shoreham site were collected across an aggregate extraction area over 4 years with the aim to test several habitat mapping techniques by documenting the presence of different faunal levels across the area. The samples collected at the Tyne and Thames were initiated at former sewage sludge disposal sites. Cefas conducted annual sampling in these areas during and post cessation of sewage disposal after January 1999 to monitor the benthic macrofauna community.
To obtain the macrofauna, sediment samples were collected using a sediment samples collected using a Day Grab (Van Veen, 0.1m2) or a Hamon grab (either 0.1m2 or 0.25m2), depending on the area and nature of the sediments. Samples were then immediately sieved on board with running seawater over a 0.5mm and/or 1mm mesh sieve to remove the sediment. After sieving, the samples were preserved in 5% buffered formaldehyde. On return to the laboratory, the samples were washed to remove the formaldehyde and the macrofauna extracted using light microscopy and preserved in 70% Industrial Methylated Spirit. Animals were identified to the lowest taxonomic level possible and each taxon enumerated to generate the abundance information. The in some samples, the same animals were then weighed after blotting (wet weight) to the nearest 0.0001g to obtain biomass information.

Norway’s engagement with cod fishing has dated back to at least the Viking Age. Cod has been an important resource and a vital source of sustenance for the local population for centuries. Based on the stable isotope analysis technique, cod bones dating back to medieval times have been recovered at sites that were populated during this time; the configuration of these bones, with heads removed, strongly infers that advanced processing involving salting and/or drying took place well before the early modern period in Norway.

Polychaete Study in Northeastern Mediterranean Coast of Egypt

Within the frame work, organized by the National Institute of Oceanography and Fisheries, Alexandria, Egypt, 15 quantitative samples were collected and analysed for Polychaetes using a Van Veen grab on the soft bottom, at depths ranging from 12m to 106 m. Samples were taken over two seasons (spring and summer, 2008) during two trips to the Northeastern coast of the Egyptian Mediterranean waters at El Tina Bay, Balteem, Abokhashaba and Gamasa.
The analysis of samples resulted 108 Polychaete species belonging to 25 families and 61 genera. More than 50 species were considered new for Egyptian Mediterranean waters. Data were analyzed with univariate techniques (Diversity, Richness and Eveness or Equitabilty). Results showed that, species richness and abundance were lower in the deeper samples and higher in spring than in summer season. The feeding guild classification was examined. Also the relation between different depths and feeding guild were reported. A total of nine main feeding categories were identified. There were more significant associations between feeding guild and depth. Also the analysis revealed the dominance of surface deposit feeding with slightly fewer Omnivores and micro herbivores. This work, indicating that the polychaetes of the study area are quite diverse and poorly in number of individuals and great number of newly recorded species was reported.

Atlantic grey seal breeding colonies in Hay and Saddle Islands, Nova Scotia

Original provider: Duke Marine Robotics and Remote Sensing Lab Dataset credits: Duke Marine Robotics and Remote Sensing Lab Abstract: These RGB mosaics and thermal indices of Atlantic grey seal colonies at Hay and Saddle Island, Nova Scotia, were collected by small unmanned aircraft systems (UAS). The mosaics and thermal indices were assessed by human analysts, who counted the seals in the mosaic and classified individuals as 'young of the year' or 'adult'.
Concurrently, an automated detection and classification model was applied to the datasets and compared to human counts. Purpose: These datasets were used to assess Atlantic grey seal populations and to compare and test wildlife survey methods. Supplemental information: The downloadable shapefile includes TIFF images of RGB mosaics and thermal indices. The size of the zipped file is 1GB and may take a long time to download. Within the dowloaded file, the 'Analysis Materials' folders contain point shapefiles of the seals counted and classified by human analysts. In addition, the folders contain the landscape masks that were applied to the thermal indices before running the automated detection models.
