©2020 Biological and Chemical Oceanography Data Management Office.This dataset provides the counts for larvae and some later life stage benthic fauna, identified to varying levels of taxonomic granularity, collected with a large-volume plankton pump near deep-sea hydrothermal vents on the East Pacific Rise on 13 cruises from 1998 to 2025. Sampling for this 27-year time series of larval abundance was conducted using a plankton pump (McLane WTS-LV50) filtering up to ~40 cubic meters over 63-micron mesh. Specimens were preserved in ethanol and identified morpholo...

These numbers come from web analytics and reflect real user activity on the site. They reliably show dataset usage and are mostly free of bot traffic.
Sampling for this 27-year time series of larval abundance was funded by multiple awards and projects.
