North American Sessile Marine Invertebrates

The North American Sessile Marine Invertebrate Survey is conducted with settling plates to monitor native and invasive species. Data are available at OBIS. The OBIS compiled data includes species name, individual count, lat/lon, and some environmental correlates like depth and salinity.

Data Collection Summary / Methods: Invertebrate collecting devices called settling plates are deployed at marinas, commercial and military docks in several embayments each year. Settling plates are constructed of both wood and PVC (polyvinyl chloride) so that both wood-boring species and hard surface foulers can be collected.

Data collected:

OBIS data schema: species name, individual count, date, location, temperature, depth, salinity, nitrogen, oxygen, silicate.
