Long term zooplankton monitoring with the ZooScan
-Insights from a 8 years project at the Observatory of Villefranche sur Mer
and - Perspectives for a network of observation of whole plankton
Point B zooplankton time series is one of the longest and most complete in Europe
TS1: 1966-2011, Regent Net (680µm mesh), oblique hauls 0-75 m, daily sampling TS2: 1966-2003, Juday Bogorov net (330 μm mesh), vertical hauls 0-75 m, daily samplingTS3: 1995 – 2006, WP2 net (200µm mesh), vertical hauls 0-75 m, weekly samplingTS4: 2003-2011, WP2 net (200µm mesh) , vertical hauls 0-75 m, daily sampling
too many samples to analyse in a traditionnal way
More than 20 000 net samples but pooled in weekly jars (>5000 jars).
Partially analysed for target species until 1993 Degradation of the samples (formaldehyd leackage)
State of the collection in early 2004
RADEZOO service proposed 3 complementary solutions for long term preservation and analysis.
