Scientific research expeditions were aboard the RVIB Nathaniel B. Palmer in 2008 to the Antarctic Peninsula and 2013 to the Ross Sea. The time-lapse system employed a YoYo camera system comprised of an ocean imaging systems (OIS) DSC 10,000 digital still camera with an OIS 3831 strobe. It was deployed on the seafloor on an aluminum tripod with the camera elevation of 163 cm and a camera angle from horizontal (inclination) of 45 degrees. The interval between photos in the time-lapse mode was 12 h. The time-lapse camera was located on the west Antarctic Peninsula shelf floor at Station B (64 46.4200S, 65 23.6690 W) at a depth of 599 m. Images of the enteropneust and its tube were obtained from 28 July to 2 August 2008.

Extracted from the NSF award abstract:
The research will explore the genetics, diversity, and biogeography of Antarctic marine benthic invertebrates, seeking to overturn the widely accepted suggestion that benthic fauna do not constitute a large, panmictic population. The investigators will sample adults and larvae from undersampled regions of West Antarctica that, combined with existing samples, will provide significant coverage of the western hemisphere of the Southern Ocean. The objectives are: 1) To assess the degree of genetic connectivity (or isolation) of benthic invertebrate species in the Western Antarctic using high-resolution genetic markers. 2) To begin exploring planktonic larvae spatial and bathymetric distributions for benthic shelf invertebrates in the Bellinghausen, Amundsen and Ross Seas. 3) To continue to develop a Marine Antarctic Genetic Inventory (MAGI) that relates larval and adult forms via DNA barcoding.
