Plankton
Global Map of Zooplankton
Figure: Global map of current zooplankton observations. Black points show CPR samples, red points indicate long term zooplankton sampling stations that could provide diversity measurements (note that this map is incomplete with regard to zooplankton monitoring stations).

ECV Products and Requirements
These products and requirements reflect the Implementation Plan 2022 (GCOS-244).
The requirements are found in the complete 2022 ECVs Requirements document as well: ECV Plankton.

(*) Goal (G): an ideal requirement above which further improvements are not necessary. Breakthrough (B): an intermediate level between threshold and goal which, if achieved, would result in a significant improvement for the targeted application. The breakthrough value may also indicate the level at which specified uses within climate monitoring become possible. It may be appropriate to have different breakthrough values for different uses. Threshold (T): the minimum requirement to be met to ensure that data are useful
