Expedition NewYork

 

After tagging nine juvenile white sharks and confirming the first known nursery in New York waters back in 2016, OCEARCH and its team of multi-institutional scientists are returning to Long Island, NY. The team goal is to increase the sample size needed to complete the North Atlantic White Shark Study that was started in 2012. The data will also contribute to a variety of studies performed by our science partners.

FAQ - NY Expedition II

 
Where is the research expedition taking place?
The expedition will take place in Montauk, NY
When is the research expedition?
The expedition begins on Aug. 5, 2017 and ends on Aug.24. The expedition will kick off with a ship tour on Aug. 5 in Montauk, NY, and the research will begin on Aug. 6th. There will be more outreach events at the end of expedition - Aug. 25-27. Make sure to check the NY Expedition microsite for details.
How many researchers are embarking on this expedition?
There are 13 researchers, from 11 institutions, embarking on the expedition. There are also 11 other scientists from 9 institutions receiving samples collected from the sharks.
Which institutions will be participating and/or receiving samples from this expedition?
The expedition will include scientists from NOAA National Marine Fisheries Service, Mote Marine Laboratory, Wildlife Conservation Society’s New York Aquarium, Southampton Schools, Florida Atlantic University, New Jersey Institute of Technology, Stony Brook University, University of South Carolina - Beaufort, Adventure Aquarium, University of Massachusetts, Woods Hole Oceanographic Institution, Auburn University, College of Charleston, University of Florida, Cape Canaveral Scientific, Georgia Aquarium, Georgia Southern University, VithajSafari South Africa, University of New Haven, Mississippi State University, University of Massachusetts - Dartmouth.
What are your objectives for this expedition?
This is OCEARCH’s second expedition in Montauk, NY. ​OCEARCH and its team of collaborating scientists are embarking on their 30th expedition to tag juvenile white sharks. The team’s goal is to gather data on the ecology, physiology, and behavior of sharks in the Atlantic Ocean, and to increase the sample size of the research started in 2012 in Cape Cod, MA. 
What has OCEARCH learned from the previous expedition it held in Montauk, NY?
During the three-week expedition in the waters off Montauk, OCEARCH and its collaborating scientists tagged 9 juvenile white sharks, thereby confirming the first known nursery - and likely birthing site - for the North Atlantic great white shark.
What species will you focus on?
Researchers will focus on juvenile white sharks
Can you describe your process for tagging a shark?
Sharks are caught from tenders using handlines and are guided by hand in the water on and off the lift. After capture, sharks are brought to the submerged platform of the M/V OCEARCH vessel and the platform is raised. Once the sharks are restrained and hoses of water have been set to enable the flow of oxygen, they are measured. SPOT, acoustic and accelerometer tags are attached and tissue and blood samples are collected. 
What samples will you collect from the sharks?
Once caught, the sharks will be measured, sexed, tissue will be collected (blood, muscle and fin clip) and the sharks will be tagged with satellite and acoustic transmitters. Small fin clips are removed with a pair of scissors, a muscle sample is removed from the flank with a 8mm biopsy punch and blood is taken from the caudal vein. 
Will the sample collection and studies impact the shark’s health?
While the tagging method, which has been used on sharks and other species for over a half century may cause some level of brief discomfort, there is no scientific evidence that it impacts their behavior or survival post-release. In fact, data from the Global Shark Tracker provides strong evidence that the animals tagged using this method show long-term survival and long-distance migrations indicative of normal function and reproductive cycles.
What studies will you run from the samples?
Scientists will assess the physiological effects of capture stress in the white shark, including characterizing post release recovery; assess the reproductive condition, reproductive cycle, gestation period, and fecundity of white sharks in the Atlantic Ocean; understand parasite species presence, abundance, and infection sites in white sharks; perform comparative analysis of DNA sequence variation in the white shark; study contaminants of emerging concern in white sharks from US Atlantic waters, including flame retardants, pharmaceuticals, and other anthropogenic pollutants released into aquatic environments; develop values for trace minerals, vitamins, and fatty acids for white sharks; and identifying mutualistic interactions between bacteria and host organisms.
What does the tracking data from the Global Shark Tracker tell us about sharks?
The data allows us to see the range of shark movements in different parts of the world - their migration patterns - and helps us uncover the areas in need of protection. The tracking data allows studies such as the examination of fine and broad-scale movements, habitat use, site fidelity, residency, and feeding behavior of white sharks. The data we’ve enabled so far, has allowed scientists to figure out the mating and breeding sites of the species on the west coast of Mexico – Guadalupe Island. Scientists have also documented the first migration of Great White Sharks to the gulf, and the mid-Atlantic ridge.
What happens to the data you’ve collected?
The data is shared in an open source environment with collaborating institutions that utilize it to conduct studies that are eventually published in peer-reviewed scientific journals. The papers, which can take 2-5 years to publish, are used to assist in policy decisions.
How can I follow the expedition?
