A collection of marine life surveys collated by the Marine Life Information Network (MarLIN) as part of their data access program. Surveys are either flagged as professional surveys or data collected by volunteer recorders as part for the Sealife Survey. Information about survey methodology can be found on the MarLIN Web site (www.marlin.ac.uk). There are currently 368 surveys collated by MarLIN containing 250,000 species records. Data ownership remains with the data provider and permission must be sought for commercial use of the data.

Current profile data from Downward-looking ADCP #00 on FPF Marlin, 2.911000e+01N, 8.794000e+01W, 2005/11/01 00:05 through 2005/12/29 23:59

Southern blue fin tuna have been released since 1959 using conventional tags. This is where the tag database has its origins and therefore a large amount of the data held in the database consists of conventional (dart) tags releases of this species in Australian waters. In recent times the data base has evolved to include many more species of pelagic and benthic fish, sharks and turtles. The advent of electronic tags, some with satellite and/or acoustic tracking ability has added to the complexity of the database. Not only do these electronic tags require additional fields for setup options before release, but also require tables to support the complex range of data retrieved from these tags. The data has been grouped into a number of projects. The purposes behind each such project are many and range from the collection of data required for population analyses (the estimation of mortality rates and growth rates), to the investigation of large and fine scale movements, feeding patterns as revealed by the use of ‘smart tags’. Also for many tagging programs there have been changes in tagging ability between skilled and novice taggers. Individual projects thus reflect these criteria so that each Marlin entry contains as nearly as possible a homogenous data set in terms of: 1. Species 2. Tag type 3. Taggers used, in particular the use of CSIRO or non CSIRO personnel 4. Period of coverage to ensure that particular variants of tag type were used 5. Specific project aims 6. Specific geographical area 7. Lead agency ( to ensure that appropriate permission is obtained before access to the data base is permitted) Thus all the species specific data contained in the CSIRO data base has been grouped into discrete Marlin metadata units. Tag data for a particular species may also be covered by multiple Marlin units. The CSIRO database manager has a full listing of the species numbers contained in all Marlin units. Species where more than 200 individuals have been tagged in individual or multiple projects are listed in the descriptive keyword section. Keywords: Tag, Conventional, Archival, Acoustic, Pop-Up, Satellite, Tuna, Swordfish, Shark, Pelagic Fish, Demersal Fish, Turtles.

Large pelagic fishes are often broadly and continuously distributed and capable of long-distance movements. These factors can promote gene flow that makes it difficult to disentangle intra- vs. inter-specific levels of genetic differentiation. Here, we assess the relationship of two istiophorid billfishes, white marlin (Kajikia albida) and striped marlin (K. audax), presently considered sister species inhabiting separate ocean basins. Previous studies report levels of genetic differentiation between white marlin and striped marlin that are smaller than those observed among populations of other istiophorid species. To determine whether white marlin and striped marlin comprise separate species or populations of a single globally distributed species, we surveyed 2520 single nucleotide polymorphisms (SNPs) in 62 white marlin and 242 striped marlin sampled across the Atlantic, Pacific, and Indian oceans. Multivariate analyses resolved white marlin and striped marlin as distinct groups, and a species tree composed of separate lineages was strongly supported over a single lineage tree. Genetic differentiation between white marlin and striped marlin (FST = 0.5384) was also substantially larger than between populations of striped marlin (FST = 0.0192–0.0840), and we identified SNPs that allow unambiguous species identification. Our findings indicate that white marlin and striped marlin comprise separate species, which we estimate diverged at approximately 2.38 Mya. Methods This dataset comprises raw genotypes for genome-wide SNPs produced by Diversity Arrays Technology (https://www.diversityarrays.com/) using DArTseq methodology (Sansaloni et al. 2011 BMC Proceedings). These data have not undergone any additional quality filtering. Genotypes in this dataset correspond with n = 242 striped marlin (Kajikia audax) sampled across the Pacific and Indian oceans and n = 62 white marlin (K. albida) sampled across the Atlantic Ocean. These data were produced using a digestion with the PstI and SphI restriction enzymes and used for 77-bp single end high-throughput sequencing on an Illumina HiSeq 2500.

This visualization product displays the cigarette related items abundance of marine macro-litter (> 2.5cm) per beach per year from Marine Strategy Framework Directive (MSFD) monitoring surveys without UNEP-MARLIN data.

EMODnet Chemistry included the collection of marine litter in its 3rd phase. Since the beginning of 2018, data of beach litter have been gathered and processed in the EMODnet Chemistry Marine Litter Database (MLDB).

The harmonization of all the data has been the most challenging task considering the heterogeneity of the data sources, sampling protocols and reference lists used on a European scale.

Preliminary processings were necessary to harmonize all the data:

• Exclusion of OSPAR 1000 protocol: in order to follow the approach of OSPAR that it is not including these data anymore in the monitoring;

• Selection of MSFD surveys only (exclusion of other monitoring, cleaning and research operations);

• Exclusion of beaches without coordinates;

• Selection of cigarette related items only. The list of selected items is attached to this metadata. This list was created using EU Marine Beach Litter Baselines, the European Threshold Value for Macro Litter on Coastlines and the Joint list of litter categories for marine macro-litter monitoring from JRC (these three documents are attached to this metadata);

• Selection of surveys referring to the UNEP-MARLIN list: the UNEP-MARLIN protocol differs from the other types of monitoring in that cigarette butts are surveyed in a 10m square. To avoid comparing abundances from very different protocols, the choice has been made to distinguish in two maps the cigarette related items results associated with the UNEP-MARLIN list from the others;

• Normalization of survey lengths to 100m & 1 survey / year: in some case, the survey length was not exactly 100m, so in order to be able to compare the abundance of litter from different beaches a normalization is applied using this formula:

Number of cigarette related items of the survey (normalized by 100 m) = Number of cigarette related items of the survey x (100 / survey length)

Then, this normalized number of cigarette related items is summed to obtain the total normalized number of cigarette related items for each survey. Finally, the median abundance of cigarette related items for each beach and year is calculated from these normalized abundances of cigarette related items per survey.

Sometimes the survey length was null or equal to 0. Assuming that the MSFD protocol has been applied, the length has been set at 100m in these cases.

Percentiles 50, 75, 95 & 99 have been calculated taking into account cigarette related items from MSFD monitoring data (excluding UNEP-MARLIN protocol) for all years.

More information is available in the attached documents.

Warning: the absence of data on the map does not necessarily mean that they do not exist, but that no information has been entered in the Marine Litter Database for this area.
