KRILLBASE: a circumpolar database of Antarctic krill and salps
Standardised monitoring of Euphausia superba and salps only dates from the 1990s and in a few sites. However a wealth of historical data exists from various countries, all focussing on a narrow slice of Antarctica. KRILLBASE has mined and compiled all available scientific net-haul data into a single searchable database. This active project so far contains ~15000 net hauls for abundance of salps and postlarval krill, with many individual krill length measurements. The best coverage is December-March in the Atlantic and Indian sectors (1926-1939, post-1976). This composite dataset needs careful analysis because the methods were not standardised. However it is more than the sum of its parts and allows a diversity of analyses, for example meso- and circumpolar scale dynamics, changes with time and krill demographics. KRILLBASE includes state-funded programs (see above) which require direct prior communication for access to their parts of the dataset.
