Marine scientists use JeDI to create world's first global jellyfish database
Date:5/15/2014

An international study, led by the University of Southampton, has led to the creation of the world's first global database of jellyfish records to map jellyfish populations in the oceans.

Scientific and media debate regarding future trends, and subsequent ecological, biogeochemical and societal impacts, of jellyfish and jellyfish blooms in a changing ocean is hampered by a lack of information about jellyfish biomass and distribution from which to compare.

To address this knowledge gap, scientists used the Jellyfish Database Initiative, or JeDI, to map jellyfish biomass in the upper 200m of the world's oceans and explore the underlying environmental causes driving the observed patterns of distribution.

"The successful development of this first global-scale database of jellyfish records by the Global Jellyfish Group was due, in large part, to the incredible generosity of members in the international jellyfish research and wider scientific communities," says lead author of the study Dr Cathy Lucas, a marine biologist from the University of Southampton.

"With this resource, anyone can use JeDI to address questions about the spatial and temporal extent of jellyfish populations at local, regional and global scales, and the potential implications for ecosystem services and biogeochemical processes," adds Dr Rob Condon of the University of North Carolina Wilmington in the USA.

Using data from JeDI, the authors were able to show that jellyfish and other gelatinous zooplankton are present throughout the world's oceans, with the greatest concentrations in the mid-latitudes of the Northern Hemisphere. In the North Atlantic Ocean, dissolved oxygen and sea surface temperature were found to be the principal drivers of jellyfish biomass distribution.

The spatial analysis carried out by the researchers is an essential first step in the establishment of a consistent database of gelatinous presence from which future trends can be assessed and hypotheses tested, particularly those relating multiple regional and global drivers of jellyfish biomass. It complements the findings of a 2013 study, led by Dr Condon, in which global jellyfish populations were shown to exhibit fluctuations over multidecadal time-scales centred round a baseline. "If jellyfish biomass does increase in the future, particularly in the Northern Hemisphere, this may influence the abundance and biodiversity of zooplankton and phytoplankton, having a knock-on effect on ecosystem functioning, biogeochemical cycling and fish biomass," says Dr Condon.
