Abstract:
These data are gonad index (gonad mass/total animal mass) and egg size measurements for two Antarctic marine invertebrates, the starfish Odontaster validus and the brittle star Ophionotus victoriae. Data are for samples hand-collected monthly, where weather permits, by scuba divers from sites near the British Antarctic Survey's research station at Rothera Point, Adelaide Island. Samples were first collected in 1997 and have continued for 19 years to 2015.

| Quality: | Data are raw values quality checked after entry into the spreadsheet. | |
| Lineage: | The data are for gonad weights or counts made from histologically prepared slides in Southampton University (for more information contact Dr Laura Grange, National Oceanography Centre, University of Southampton). Slides were made from gonad samples from specimens collected monthly from South Cove or Hangar Cove, Rothera Point, Adelaide Island and preserved in 4% buffered formaldehyde. | |
