Abstract. Copepods are often the predominant taxa in marine zooplankton and play an important role in the food web as intermediators between primary producers, the microbial loop and higher trophic levels. Due to their short life cycles and their rapid response to changing environments they are good indicators for ecosystem health and status. Investigating the effects of environmental change on planktonic copepods and thus the pelagic ecosystem requires data on species abundance and distribution. Here, we present 33 data sets with abundance and occurrence of planktonic copepods from 20 expeditions to the Southern Ocean (Weddell Sea, Scotia Sea, Amundsen Sea, Bellingshausen Sea, Antarctic Peninsula), one expedition to the Magellan region, one latitudinal transect in the Eastern Atlantic Ocean, one expedition to the Great Meteor Bank and one expedition to the northern Red Sea and Gulf of Aqaba. In this data compilation a total of 349 stations between 1985 and 2005 were archived. These data sets are now freely available at PANGAEA via the persistent identifier doi:10.1594/PANGAEA.884619. During most expeditions depth-stratified samples were taken with a Hydrobios multinet with 5 or 9 nets. On few occasions a Nansen or Bongo net was deployed. The deepest sample reached down to 2880 meter. As metadata sampling date and date/time, latitude, longitude, bottom depth, sampling depth interval, volume of filtered water and information of the net type and mesh size were recorded. Abundance and distribution data for 284 calanoid copepod species and 28 taxa of other copepod orders are provided. The taxonomic concept was consistent throughout the data sets. The density of calanoid copepod species was separately counted for females, males and copepodites. For selected species also the individual copepodite stages were counted.

Short summary
Copepods are the predominant taxon in marine zooplankton and play an important role in the pelagic food web as intermediators between primary producers, the microbial loop and higher trophic levels. Here, we provide 33 data sets with abundances for a total of 312 copepod taxa from the Southern Ocean, the Magellan region, the Great Meteor Bank and the northern Red Sea and the Gulf of Aqaba.
