Arctic Zooplankton Collections from the Chukchi Sea, 1953-1954

Zooplankton collections from 21 stations in the Chukchi Sea during August 1953 and 1954. Vertical stratified tows were conducted using a Nansen net, with accompanying temperature, salinity, and oxygen measurements. The data were collected by the Russian R/V Lomonosov under program ANII A-65 to investigate interannual changes in species composition, abundance, and distribution.

Use Cases

• Modeling interannual zooplankton abundance changes based on collection years 1953 and 1954
• Analyzing species distribution shifts in the Chukchi Sea based on stratified depth tows
• Correlating zooplankton biomass with measured environmental variables like temperature and salinity
• Investigating the influence of Bering Sea water influx on Arctic shelf ecosystems based on described species composition

Strengths

• Includes environmental measurements (temperature, salinity, oxygen) at each sampled depth layer
• Samples from 21 stations across two consecutive years (1953, 1954) for temporal comparison
• Data is geo-referenced, providing spatial context for the collections

Limitations

• Last updated 1954-08-27 23:59:59.999000; freshness should be verified
• Column-level documentation is absent; field semantics must be inferred after download
• Description notes translation issues between Cyrillic and English spellings may affect analysis
