Norfish: Shetland Cod Fishery 1520-1796

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.
Shetland is an archipelago situated off the north east coast of Scotland and comprises of several islands, formerly known in Old Norse as Hjaltland, later Hitland. It was referred to as Shetland by English fishers and the name endured. The Danish Sound Toll Tables of the 17th and 18th centuries record that cod and herring catches were exported to the Baltic. While little statistical information is known about the early Shetland fishery, from the 1740s customs records provide figures for exports of cod to Ireland, Scotland and England, and in the latter half of the 18th century increasingly to the Mediterranean.
Zooplankton community of Shirazi bay (Kenya) sampled between April and December 1998

The data were digitized by VLIZ from the original report: Anyango, C. (2000). The zooplankton community of Shirazi Bay, Kenya. MSc Thesis. VUB: Brussel. 81 pp.
The species composition of the zooplankton community of Shirazi Bay, Kenya was studied in 1998. A total of 30 samples were analyzed. Chlorophyll a, biological oxygen demand and dissolved oxygen concentrations were also determined each time, and were later used to analyse the species data. Maximum values of zooplankton abundance were reported in mid-April (1161 ± 169 indiv.m^-3), and the lowest was at the end of April (300 ± 35 indiv.m^-3). Total abundance of zooplankton varied from 911 ± 165 indiv.m^-3 in station 3 to 262 ± 54 indiv.m^-3 in station 5. The most important taxa encountered included: Calanoida, Brachyura, Oikolpeura, Amphipoda, Mysidaceae, Polychaeta and Chaetognatha. Calanoida was the most dominant taxon sampled and it made up 46% of the total zooplankton abundance.

ImageDOP Bentic Video Annotations in the Faial-Pico Channel in 2011

Annotations of species recorded on video by Remote Operated Vehicle (ROV) during dives performed in the Faial-Pico Channel in the Azores archipelago, Portugal. Videos were recorded between 80 and 250 meters depth.
Several ROV dives in 2011 collected imagery date between 80 and 255 meters depth, extending from Monte da Guia to the circalittoral off Criação Velha in Pico Island (Gomes-Pereira et al. 2014). Benthic sessile and mobile megafauna of conspicuous morphotype, or larger than circa 10 cm, as well as all icthyofauna present, was logged on to a database with the customizable video annotation software COVER (Ifremer). The ROV SP ( SeaBotix LBV300S-6 ; IMAR-DOP/UAz), was operated from the R/L Águas Vivas. The ROV was equipped with a colour camera (570 line/02 Lux, 4:3), with four lights installed externally on the four front corners (480 Lumen each) and a scaling two-point laser system (5 cm apart) that was used to estimate sizes. ROV SP was positioned with a Subsea Micron Nav USBL (Ultra Short Baseline) unit fitted onto the vehicle in the responder mode. The navigational data were manually filtered for outliers and smoothed with a moving average, to remove false loops. The moving average allowed adjusting the resulting dive track (Gomes-Pereira and Tempera 2015).

The database comprises taxonomic and quantitative data (individuals count, density and biomass per square meter) for 97 macrobenthic species and 5 supraspecific groups.
Cetacean coordinated transborder monitoring using ferries as platforms of observation off Tunisia 2013-2014 - Ketos

Within the framework of the ACCOBAMS agreement a partnership of Italian and Tunisian research bodies is investigating the presence of cetacean, and the relationship with maritime traffic, within the region comprise among Tunisia-Sicily-Sardinia considered a critical habitat for cetacean species. To be able to systematically investigate the region, especially in high sea areas and all year round, ferries are used as platform of observations. Floating marine litter is experimentally investigated.

Infaunal abundance and biomass from sediment grabs in Belfast Lough as part of a habitat mapping project in 2018

This dataset contains information on infaunal abundance - biomass from sediment grabs in Belfast Lough as part of a larger - ongoing habitat mapping project. The sediment - infaunal survey was carried out in January 2018 by AFBI and this dataset was integrated into the larger mapping project since 2012.  The project is joint with the British Geological Society and Belfast Harbour with the aim of mapping the seabed floor and updating it from more historical information.
The seabed mapping was carried out on the White Ribbon vessel (British Geological society) using Kongsberg EM3002D multibeam and on the FPV Banríon Uladh using the same multibeam system. The sampling in 2018 (this dataset) was carried out on board the RV Corystes using a day grab. Particle size analysis (PSA) was carried out and the infaunal samples were sent away to accredited taxonomic laboratories to be indentified. The most abundant species recorded was the echinoderm Amphiura filiformis and the most frequently recorded (present in all samples) was the hydrozoan sertulariidae.  
"This dataset contains information on infaunal abundance and biomass from grab samples carried out in Belfast Lough on 2018-01-23. This survey is part of a larger, ongoing project (since 2012) joint with Belfast Harbour and the British Geological Society (BGS). The Habitat mapping project of Belfast Lough used the BGS vessel White Ribbon and Fisheries Protect Vessel Banríon Uladh as both of these were fitted with Kongsberg EM3002D multibeam. Most previous/ historic information about the seabed in Belfast Lough were collected using single beam or lead line surveys which are not as accurate as multibeam. Therefore this project is important to allow a more comprehensive and in depth survey to be done of the seabed in Belfast Lough. The multibeam surveys ran from 2013-07-29 to 2013-08-13, with all depths surveyed being less than 0.5m deep.
This grab sample survey (2018) is part of a larger project in Belfast Lough to map out the sediment and seabed to provide a baseline for sediment transport studies and to create habitat maps for management. The information in this dataset was collected on board the RV Corystes in 2018 using a 0.1m2 day grab. The methodology used for collecting samples in the day grab is detailed below.
• A 0.1m2 day grab was used to take a sample of the sediment - associated infaunal communities.
• When the sample reaches the deck, a 250ml sample is taken for PSA and a further 25ml is taken for C - N analysis. The rest of the sample is carefully sieved to reveal any infauna.
• Fixed Formalin (4% buffered formaldehyde) is added to the remains of the sample and these are placed in labelled buckets.
• The samples are sent to accredited taxonomic laboratories were they are identified to as high a level as possible and weighed.

To get an idea of the demersal fish fauna the shallow sub littoral (3-4 m at low water) of the sandy beach, in front of the nature reserve of "het Zwin" was sampled with the help of a 1.90 m fine-meshed (10 mm straightened mesh) tree-dredge-net in 1985. Some basic ecological parameters such as seasonally occurence, density and biomass were measured. Furthermore, the composition of the diet is evaluated for the species Agonus cataphractus, Liparis liparis and Pomatoschistus minutus, by means of stomach analysis.
