THE
LOG FROM THE OUTER BANKS/THE 2000 ANNUAL SEAMAP TAGGING CRUISE

Date:
Saturday, 1/29/00
Time:
2110 (9:10 PM to the landlubber)
Position:
35.12 N 75.38 W Just southwest of Cape Hatteras, approximately
5 miles offshore.
The
NOAA ship Oregon II (Pictured at left and from the stern
of the vessel) got underway this morning at 0830, after waiting
for daylight to make the run out of the shoals around Morehead City.
The scientific party was made
up from members of various coastal State agencies, the U.S. Fish &
Wildlife Service and the National Marine Fisheries Service. So far the
seas have been relatively calm, ranging up to three feet, and winds
have been blowing in the 15-20 knot range. Outside air temperature is
in the mid thirties. So far so good with the weather, although they
are predicting a low pressure system will move through tomorrow evening,
which may make things a bit rougher. We started fishing about 3 in the
afternoon, setting two trawl nets, one off each side of the ship. It
took a few sets to get all the kinks out of the gear, the deck crew,
and especially the scientists! All seems to be working well now--all
we need now is the rocks! (oops--stripers. I discovered that they are
only called rockfish in Maryland--and I'm the only Marylander aboard).
We've only gotten four so far. We are knee-deep in juvenile croaker,
spot and weakfish, however (literally knee-deep after a few of these
tows). Other than the small things, we've caught a moderate amount of
dogfish, a few skate, and three monkfish
(while delicious, they definitely win the "Ugliest Fish" contest--they
seem to be all mouth and teeth. The real high-light so far has been
the four foot Atlantic sturgeon that appeared in one haul--these are
pretty rare along the coast these days, and are under a forty-year fishing
moratorium. We tagged it three different ways and sent it along its
way. All right gotta run-- I hear the penetrating whine of the trawl
winches--another bag is coming aboard. Doing science out here is like
having Christmas once an hour--you can never wait to see what surprises
await you in the cod-end!
Date:
Sunday, 1/30/00
Time:
1615
Position:
35.38 N 75.24 W About half way between Hatteras and the
Oregon Inlet, a few miles off the beach.
The
weather continues to be not that bad (knock on wood)--its quite gray
and cloudy, with intermittent showers, but warmer--in the mid forties,
with 20 knot winds and four foot seas. The much discussed low-pressure
system seems to be spooling up--the barometer is starting to drop. The
stripers continue to elude us--mostly. We did have one good tow just
off Cape Hatteras where we got 43 tagged. The thing that stands out
most to me is the large sizes compared to what we see up in the Bay--most
of the fish we are getting are nearly three feet long. I've only seen
one so far that would be below the eighteen inch limit in the bay! We've
made a few adjustments to the nets so they are fishing a bit cleaner--meaning
less shoveling of juvenile croaker, spot and weakfish. We've also moved
up into the land of the bay anchovy (a favorite of mine--the subject
of my masters' thesis). During daylight hours we are constantly followed
by a cloud of seabirds. A lot of diving gannets (which to me look like
blue-footed boobies)-their distinctive "Waak-waak-waak" cry always make
me think they find something funny about all these orange-jacketed humans
catching tons of fish and just shoveling them off the stern for them
to feast on. We're seeing scads of juvenile seagulls in light-brown
plumage, and also plenty of pelicans. We're quite popular with the avian
set. Other than the fishing, we're all preparing to watch the Superbowl.
With its DSS system, the Oregon II gets about 10 times as many TV channels
as my rabbit-ears back home! I'll be able to catch the first half, but
will be on watch starting at 2000, so I'll miss the second half--Go
Rams! Operations are ongoing, 24 hours
a day.

Well,
we've finally found the fish! We've tagged nearly 3,000 so far--including
over 900 in one four hour watch yesterday! There is a semi-friendly
competition among the three watches of scientists to see who can tag
the most fish. It is mostly friendly, but, well, lets just say that
there was a rules committee formed. Send a bunch of bureaucrats to sea
and what do they do? Form committees! The fish we are getting are mostly
smaller--in the 15 to 18 inch range--but there sure are lots of them!
We're probably averaging a couple hundred per tow in certain areas.
If we keep up this pace, it should be a record-setting year for number
of rockfish tagged (the record: in 1994 5,302 fish were tagged). As
a matter of fact, we're having more tags rushed down to Duck, NC, tonight,
as we should have used up the 5,000 we brought along by sometime tonight
or tomorrow! (The zodiac pictured here
heading into shore for more tags)The ships small boat runs into shore
at Duck, NC to get more tags.") Of course all these fish mean lots of
work for us scientists. This is billed as a 'cooperative tagging cruise,'
supported by the many state and federal agencies that have an interest
in striped bass. We have people on board from the National Marine Fisheries
Service, the U.S. Fish and Wildlife Service, the North Carolina Division
of Marine Fisheries, the Virginia Marine Resources Commission, the Atlantic
States Marine Fisheries Commission, and of course the Maryland DNR!
So far, everyone has been very cooperative indeed! There is no way one
watch could process the hundreds of fish that are coming aboard at a
time, so everyone pitches in to help out. Some of us are starting to
get a bit sleep deprived, but we had a brief respite of light catches
this morning. The run into Duck for more tags should provide a respite
as well. The weather continues to cooperate--its cool--in the low 40's,
but 15-20 knot winds keep us (and the fish) well chilled. That's great
for the fish--cold air temperatures lower their stress levels--but a
bit harder on the taggers! Still, it could be a lot worse. The seas
are still pretty flat. We've only had one day where we were really rolling,
and only a couple of scientists temporarily lost to sea-sickness. Hopefully
the good conditions and good fishing will keep up!

The
weather warmed up a bit today, with temperatures reaching into the 50's.
If I seem to be discussing the weather a lot, that's because it matters
so much out here. On shore, discussing the weather is a platitude-something
to fill conversational space. At sea, changes in the weather have a
direct impact on virtually all facets of life-it becomes a preoccupation.
Anyway, certain DNR scientists spent the delay basking in the first
warm sunshine of the cruise. Sitting up outside on one of the upper
decks with sunglasses, a magazine and a lawn chair in near 60 degree
warmth, it was hard to tell that I was on a research ship and not on
the 'Lido Deck' of the Love Boat! While completing one tow, we were
tantalized by a huge flock of seabirds a couple of miles off to starboard
who were wheeling and diving, clearly working on a school of small fish.
Any commercial fishermen will tell you that's the place to be! As the
birds work what was probably a school of herring or menhaden from above,
the stripers are probably working them from below. As a marine scientist
I have always been told that the open ocean isn't always homogenous,
but that there are 'patchy ' distributions and concentrations of fish
and other animals. It is one thing to learn this in a lecture, quite
another to see it in action! For some reason, the school of bait fish
had concentrated in this one spot, bringing all their predators along
with them. Anyway, we finished up one mildly productive tow, and went
charging off towards the birds. Things looked pretty good on the fish
finder/ depth sounder. We woke up the watches that were asleep so we
had 'all hands' available. The catch did not disappoint! Both sides
of the deck were covered in stripers, and we had three teams tagging
the fish at once! The catch overwhelmed our live wells-we ended up having
to throw approximately 100 fish overboard to ensure the tanks weren't
too crowded. By the time the last fish went over the side approximately
one half hour later, about 600
fish had been tagged!

All
kinds of interesting things happened today. After getting reasonable
catches of stripers this morning, we managed to hang up our trawl nets
on some underwater obstructions. Fishing operations were delayed for
a few hours while we changed one net and repaired the other. On the
next trawl, we managed to hang up the port net (again!) and fill the
starboard net so full of juvenile croaker, spot and weakfish that we
couldn't even bring it aboard! We had one of the crew hang out of the
scupper and cut the bag open to release the fish. Incredibly, we managed
to snag the one striper in the bag with a boat hook! Anyway, the port
net is beyond on-board repair, so we finished up they day fishing only
the starboard net. As we started moving south, the fish once again began
eluding us. Our hardhats got progressively more decorated through the
week (pictured at left). By this evening, it was time to start heading
back south to make port tomorrow morning. As we made our way further
off shore to clear Cape Hatteras, we started encountering 20-30 knot
winds, and the waves started picking up accordingly. I ended up on the
bridge, watching our bow smash through the 6-8
foot seas. A few were large enough that while standing in the bridge
15 feet above sea level, there was so much spray you felt like you were
in a car wash! It was exciting
enough that I ended up staying on the bridge all through dinner, just
so I wouldn't miss any of the action (a few other scientists skipped
dinner for other reasons!). I had the unique experience of seeing several
dozen sunsets tonight-we were pitching enough that just as the sun was
about to set, every time we pitched up on a wave you could just see
the top of the sun, and as we pitched back down, it would disappear
below the horizon. Then we would pitch up, it would briefly reappear,
etc. etc. All in all, it was a spectacular ending for our last day at
sea. The Oregon II returned to Morehead City on February 4th. The cruise
was a spectacular success-over 6,400 rockfish were tagged, using nearly
every tag available on the east coast! Many of these fish will be caught
and their tags reported by recreational and commercial fishermen, providing
scientists and managers with valuable data for years to come.
