Info on current shark goings on


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

White shark info gets lost to shark biologists because of stringent FEDERAL
possesion rules. Here is a discussion on that subject, about a large white off Chatham
MA on December 18th 2010

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
On July 30, 2012, around 3:30 PM, a white shark bit the feet and leg of a swimmer/body surfer, at
Ballston Beach Truro Mass. The beach is on the ocean side of Cape Cod. (Lat 42 - 00')
Truro is the next town to Provincetown.

Updated - June4, 2014 White shark tagging info.

From 2009 thru 2013, the Massachusetts Div. of Marine Fisheries, has tagged 38 white sharks off
Chatham, Mass., using
28 acoustic tags - 20 satelite tags and 5 spot tags. (some sharks have more
than one type of tag attached.)

Tagging white sharks is expensive, and the State is basically out of money for white shark and
sandtiger shark research or more would have been tagged.
For white sharks, the tags are about $4,500, plus you need to hire a boat, and a spotter plane.

Chris Fischer on the "Ocearch" platform boat, came to Chatham Mass., the end of last summer and
tagged 2 white sharks in mid-September 2012, using both spot tags, and acoustic tags.
some of the new acousic shark tags, could give reliable results for for up to ten years.

The two white sharks that were tagged by Chris Fischer off Chatham Mass. in 2012 were named
Genie (after Dr. Eugenie Clark) and Mary Lee (after Chris Fischer's mother)
Fischer tagged 2 more white sharks off Chatham in 2013.

Fischer uses a spot tag. The spot tag, which is bolted to the dorsal fin, after the shark is removed
from the water on a platform, gives the Lat/Lon of the shark when its dorsal fin breaks the surface of
the water. The longer the dorsal is up, the more accurate the positioning. So you get immediate
knowledge of where and when the shark is swimming on the surface with this type of tag. You don't
have to wait months to find out where the shark was. (Unless the shark stays down below the
surface, which some sharks do for months at a time.)

The satelite tags get detailed data on salinity, depth, water temp etc.- but you have to wait months
for the programmed tags to release, and the information sent by satelite.

Acoustic tags were also added to these two white sharks, Genie and Mary Lee, and will send a
constant unique signal that can be picked up by hydrophones strategicaly placed in the ocean along
the coast, if the shark passes close enough to the receivers.- roughly within 1,000 feet. Or as
biologists like to say, 300 meters. About 25 of these hydrophone receivers will be placed by the State
from Nantucket to Provincetown on the east side of Cape Cod each year, and removed for the
winter. Hydrophones are up and down the coast and they can pick up shark tag signals from other
unknown taggers. If they want to cooperate they can find out whose tag it is by contacting Vemco,
who makes the acoustic tags, and giving Vemco the signal number. The manufacturer can then put
them in contact with the unknown tagger, and information on the time and location of the ping can be
shared.

The newer tagging method of white sharks using acoustic electronic tags that last for years has
proven to be effective and changed attitudes about the migration patterns.
For instance, the earlier theories a few years ago was the white sharks were here in Mass. for the
summer /fall and then went to Florida in the winter.
Recent info show basically some of that is true, but the white sharks seem be individualistic and go
anywhere they want.
Some, coming back from Florida to colder waters in the 40s, up here in mid -winter and then going
elsewhere.

Also tags show most do not hang around the seal colony at Chatham Mass. but use it as a food stop
while moving up and down the coast.
An exception might be "Julia" who ws tagged in Aug. 2011 and in the last 3 years is the first tagged
white shark to be detected by the hydrophones off Chatham, and has history of hanging around the
Chatham area during the summer and fall. The others whites are in and out of the area..



Fischer has an interactive website where you can follow the tracks of his tagged white sharks around
the world. I find the site somewhat cumbersome to use. `
You can vist it here

Remember the plotted points on that website are where the dorsal breaks the surface, and a signal is
received by the satelite. The straight lines between dots only connects them, and does not imply the
shark swam in a sraight line. Also some of the connecting lines might cross land connecting the dots.
Obviously the shark didn't-except in the case of shark Brenda Fassie that was taken in a gill net off
Africa and brought ashore. -Tom
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
New technology now allows a white shark to be tagged with a transmitter, and a small submarine
type drone can be launched that can connect with that signal, and follow the shark around.

Nat. Geo. should have some film footage of that process available in 2014 for the public to
view.-Tom




White sharks get very close to shore at Cape Cod ,as can be seen in this
tagging photo. The tagging boat has followed some of them for miles in
very shallow water to get the right shot at placing the transmitting tags.
