A swarm behaviour for jellyfish bloom detection [PDF]

open access: yesOcean Engineering, 2017
In this paper we will deal with the issue of swarm behaviour for jellyfish detection using UAVs (unmanned aerial vehicles). Swarm behaviour is inspired by the functioning of biological swarms. They are characterized by being fully distributed, scalable and fault-tolerant.

A blooming jellyfish in the northeast Atlantic and Mediterranean [PDF]

open access: yesBiology Letters, 2010
A long-term time series of plankton records collected by the continuous plankton recorder (CPR) Survey in the northeast Atlantic indicates an increased occurrence of Cnidaria since 2002. In the years 2007 and 2008, outbreaks of the warm-temperate scyphomedusa, Pelagia noctiluca , appeared in CPR samples between 45 ...

Preface: Jellyfish blooms: interactions with humans and fisheries [PDF]

open access: yesHydrobiologia, 2012
There is a general impression that jellyfish and other gelatinous organisms are increasing in number. Media, TV, and newspapers contribute to this impression. So are increases in jelly populations real, or is this phenomenon just a biased perception?
