Monk Seals*
- Fewer monk
seal pups were born in 2003 as compared to 2002 (51
vs. 71)
- Seal moms were in poorer condition
as compared to previous years, and as a result, their pups were smaller
on average.
- The survival rate of yearlings
was approximately 60%, which was the highest rate since before 1999. Thirty two of the
52 yearlings tagged in 2002 were relocated in 2003.
- A total of nine nursing pups disappeared in 2003:
Three from Trig Island, 3 from the Gins, 1 from Round Island, and 2 from East
Island.
- Shark activity in 2003 was similar to that in 2002.
Sharks were suspected of taking 3 pups. The shark activity appeared
to have shifted from Trig Island to Round Island.

Turtle
Cam
In an exciting new development, a remote controlled camera was
set up on East Island to monitor Hawaiian
green sea turtle nesting activity. The "Turtle
Cam" will eventually be hooked up to a live web-cam site
for data collection and as a learning/educational tool.
Cousteau's Voyage to Kure
In mid-July 2003, Jean-Michel Cousteau's film crew visited Tern Island
and the French Frigate Shoals to film the area for a special about
the Northwestern Hawaiian Islands, titled "Voyage
to Kure." The Cousteau crew filmed the birdlife
on Tern Island and the underwater marine
life in the Shoals. Part of the mission of Cousteau's Ocean
Future's Society trip was to raise awareness of the marine debris
problem in the Northwestern Hawaiian Islands.
Marine Debris Clean-up
Marine
debris consists of line, fishing net, floats, glass bottles, lighters,
and anything else discarded into the ocean. Much of the debris
found in the French Frigate Shoals probably comes from items cast
off of fishing vessels. In addition to being unsightly, marine
debris can pose a threat to wildlife. Some animals, such as albatrosses,
are known to ingest small items such as lighters. In some cases
the ingested trash proves fatal. Seals and turtles can become
entangled in marine debris and then drown, if underwater, or die
of exposure, if on the beach. In 2003, staff of the USFWS and
NMFS made an extra effort to remove the marine debris from the
islands and coral reefs within the French Frigate Shoals. The
NMFS seal researchers pulled out masses of line and net from the
reef, and turtle researchers on East Island boxed copper wire
for recycling and hauled off loads of oblong floats, glass, and
other trash.
