Hawaiian Bongo Net Collection

Section Responsible for Processing



Richard Young, University of Hawaii Oceanography Department, was the principal investigator. The National Science Foundation Grant OCE-8500593 supported Roger Seapy's heteropod study.


Roger Seapy sent the Materials and Methods section of his student's thesis (Daniel Nigro) which contains the tables summarizing the depth range and the volume of water filtered for each tow.

Collection Location and Dates

Plankton samples were collected during a five day cruise in April 1984 from waters southwest of Oahu, Hawaii, aboard the University of Hawaii’s R/V Kana Keoki. The study area was located in waters that averaged 2000 m in depth 11-20 km off shore. Tows were taken with 70 cm bongo nets through five depth intervals (0-50, 50-100, 100-150, 150-200 and 200-400 m).

Taxonomic Contents

The plankton samples are unsorted except for the squid paralarvae, which were removed by Richard Young, and the heteropods and shelled pteropods, removed by Roger Seapy and Daniel Nigro.


Specimen data is with Roger Seapy. We have the material and methods portion of Daniel Nigro’s thesis, and Roger Seapy’s publication (Seapy 1990).

Description of Collection

This unsorted plankton collection was originally fixed in 4% buffered seawater-formalin for 48 hours then transferred to 40% isopropanol. It is now stored in 50% isopropanol. It is presently located in the polychaete office, but will be processed in the lab then stored in the Polychaete Collection Range.
Lab processing will involve transfer to 70% ethanol, changing all lids, and finally inserting appropriate labels.

Collection Inventory

The collection consists of 64 glass jars (16 oz.) with bakelite lids. These plankton samples are in 3 plastic crates with padding between the jars.
