**Project title:** The Hidden Ocean: Explorations under the ice of the
Western Arctic -- the pelagic fauna: Phase II

**Principal Investigator and institution:** Russ Hopcroft, University of
Alaska Fairbanks

**Expedition title:** Hidden Ocean II

# Expedition dates and itinerary: June 27 -- July 26, 2005 -- Barrow, AK to Barrow, AK

# Chief Scientist and institution: Rolf Gradinger, University of Alaska Fairbanks

# Co-sponsors / partners / participating organizations: Census of Marine Life

**Vessel Identification:** USCGC Healy

# Primary Equipment: ROV *Global Explorer*, Hydrobios multi-net midi

**Geographic area of operations** South-western Canada Basin

# Summary of Expedition Objectives: 

1\) Identify the poorly known gelatinous zooplankton fauna from the
Canadian Basin;

2\) Determine the vertical distribution and quantify the abundance of
gelatinous species and their food organisms relative to the physical
structure of the water column

**Milestones Achieved:** We have succeeded in making the first
comprehensive observations of small and large zooplankton community
found to 300m depth in the Arctic Ocean. We now have a detailed
impression of the more common zooplankton species, the depth ranges over
which they occur, and records of their appearance in their natural
habitats. We have numerous first records of may species in the Arctic
(or the Amerasian Arctic) and believe between 6-10 of these represent
undescribed "new" species.

# Sample log entries: ROV and multinet logs are on file with OE.

**Summary of Digital Data Collected:** \~120 hrs of High definition
video (DVCPro HD) was recorded from the ROV. More than 1000 digital
still images were made of the organisms collected.

# Summary of outreach and educational activities: This was handled primarily by OE through the expedition web site <http://www.oceanexplorer.noaa.gov/explorations/05arctic/welcome.html> 

**Thoughts for the Future:** We will determine if the region studied is
representative for the Arctic in general, or for only the Canada Basin,
by examining the Eurasian Basins and the central ridges in future
efforts

**Summary of Expedition Operations:** All such data was collected by an
on board OE data manager, and is currently in the possession of OE. All
quantitative operations relevant to this module follow:
