dc.description.abstract | This study investigates the association between an index of mesozooplankton biomass, derived from
the Continuous Plankton Recorder survey and satellite-derived productivity fronts in the North Atlantic.
While chlorophyll-a content (CHL) is commonly described as a proxy for phytoplankton biomass, the
size of productivity fronts estimated from the horizontal gradient of CHL appears to be directly linked
to mesozooplankton biomass. Our results suggest that the lifespan of productivity fronts, which ranges
from weeks to months, meets the time requirement of mesozooplankton to develop. The proposed
indicator describes the daily distribution of mesozooplankton’s suitable feeding habitat. It also provides
a coherent interpretation of the productivity front development with respect to phytoplankton activity
(CHL values) and potential predation by higher trophic levels. Since mesozooplankton are essential
for feeding at higher trophic levels, this satellite-derived indicator delivers essential information for
research and policy. An unanticipated positive trend of the indicator from 2003 to 2017 is observed
at a basin scale under the current efects of climate change, with regional peaks in relatively poorly
productive areas. Such monitoring indicator is potentially important to advances in marine food web
modelling, fsheries science and the dynamic management of oceans towards sustainability | en_US |
