Mnemiopsis Ecology Modelling and Observation


This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled.

The MEMO (Mnemiopsis Ecology Modelling and Observation) Project was part of a wider sampling programme in collaboration with Ifremer and ULCO (France), ILVO (Belgium) and Deltares (Netherlands). The data collected were used to produce models (e.g. an Individual Biological Model, and hydrodynamic, ecosystem and socioeconomic models – Collingridge et al. (2014), Van Der Molen et al. (2015) that increased the understanding of the life cycle of Warty Comb Jellyfish (Mnemiopsis leidyi), the interactions of gelatinous zooplankton within their ecosystem and the consequences of increasing number of gelatinous zooplankton in European shelf seas for stakeholders (industry such as power plants, fisheries and tourism).

The project collected samples for analysis of fish larvae and fish eggs, microzooplankton and mesozooplankton and phytoplankton.

CEFAS Cruises:

RV Endeavour 05/2011- Western English Channel (ICES area VIIE)
RV Endeavour 05/2012 - Western English Channel (ICES area VIIE)
RV Endeavour 07/2012 - North Sea (Botney Gut/Silver Pit)
RV Endeavour 7X/2012 - North Sea

Samples were collected using 200 μm mesh ring net 0.5m diameter (for zooplankton samples) and physical data was collected via a CTD attached to a ring net.

Temperature data extracted from the CTD files.
