2012 Maritime Heritage Expedition Log by Etta Karth – July 19, 2012

Surveying for Marine Alien Species

The Marine Alien Species Team is conducting surveys for marine alien species within the Monument, inventorying non-native invertebrates at each of the stops. The purpose of their work is to better understand the distribution of established alien species and determine if there are any new alien inverts in PMNM.

Team: Scott Godwin (PMNM Resource Protection Specialist, Alien Invasive Studies), Holly Bolick (Bishop Museum, Hawaii Biological Survey Collections Manager).

Studying Coral Disease

The Coral Disease team is conducting surveys of diseased corals and studying the genetics of coral diseases. They dive with a variety of gear (hammers, clippers, vials, baggies) to collect and store coral samples. They are looking for anomalies in previously sampled permanent transect sites within PMNM to monitor changes in diseased coral.

Team: Stephen Karl (HIMB PhD lead scientist), Johnathan Whitney (HIMB Masters student), Sherril Leon Soon (HIMB Masters student), Jackie Troller (HIMB Masters student).
