The particles were released each day and run for 90 days. In the Retrospective Particle Tracks dataset a methodology of releasing an extensive set of particles over a wide area was used. This means the sets of particle tracks can be interrogated to understand connectivity between any two locations in the domain. This could be useful to understand if new human-made structures placed in any locations in the northern North Sea could potentially affect the ecological connectivity or different species with a maturity window up to 90 days. The particle tracks include location, time, age and water temperature. The data were generated under the Natural Environment Research Council (NERC) project CHASANS (Connectivity of Hard Substrate Assemblages in the North Sea) grant reference: NE/T010886/1.","keywords":"","publicationState":"citable","dataPublishedTime":"2025-04-09T15:11:00","doiPublishedTime":"2025-04-09T15:11:00","updateFrequency":"","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/44001/?format=json","dataPath":"/bodc/pol250716","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":15710031960546,"numberOfFiles":732,"fileFormat":"NetCDF"},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/12306/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/4751/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/85514/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85515/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85516/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85517/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85518/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85519/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85520/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85521/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85522/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85523/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85524/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85525/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85526/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/85527/?format=json"],"dataLineage":"The data are archived on the British Oceanographic Data Centre (BODC)'s space at the Centre for Environmental Data Analysis (CEDA) and assigned a DOI.
