Eighteen years of capture-mark-recapture (CMR) data of grey seal pups, Halichoerus grypus, from Pembrokeshire, Wales.

Eighteen years (1954-1972) of capture-mark-recapture data of 245 grey seal pups marked with identification tags in Wales. The data was obtained from paper files held by NRW and supplied originally West Wales Field Society and includes information on the location and number of animals marked in each year including sex and age estimations.

Metadata Language: English

Lineage: Seal pups were marked on beaches around the coast of Pembrokeshire covering over 100 km of National Park coastline. Seals were captured and marked with rings during the pupping season and were captured opportunistically. From detailed descriptive accounts for each individual, information of each seal’s natal colony, condition, and censorship, as well as an estimated of their date of birth and calculation of the duration of time between mark and recapture was derived. From original text descriptions of mark locations geolocated accurate positional information in a latitude-longitude format was also derived. Data collected in 1952 and 1953 were not documented in the paper files. However, a summary of records for 1952-1953 can be found in Hewer (1955).

[A] PDF and.docx copies of the scientific paper and metadata. (Comments from Tom Stringell: The work was compiled in 2019/2020 and formed part of William Kay’s PhD thesis submitted in December 2020. The paper about the pup ringing data wasn’t accepted for publication in the end so remains a chapter in the thesis.) [B] xlsx spreadsheets [C] Scan of paper field records [D] paper field records -these records were transferred to Pembrokeshire Local Authority Archive by Kate Lock NRW on 20/1/23 (Pembrokeshire Archive Unique ref. no 5714) Background Info: The orginal paper records were not owned by NRW but given to NRW; therefore permission from TNA did not have to be sought first with regards to archiving at Pembrokeshire Archive).
