Here she is, the great @MaryLeeShark herself. In the past we’ve tracked her a few times off the coast of Charleston, SC this time of year. Since white sharks stick to pretty precise migrations, there’s a chance that’s where she’s at now.

Huge shark! Watch right after the man splashes. Though it looks like a large white shark, we suspect it’s more likely a basking shark. Either way it’s big! What do you think? Video sent by Jon Azato taken 20 miles off the coast of Oregon Inlet, NC

After weathering 3 storms and grinding it out for nearly 3 weeks with no #shark sightings, we were elated to successfully sample a 1,602lb #whiteshark today. The fog lifted & Mother Ocean gifted our science team the 12' 9" subadult female we named "Acadia". #ExpeditionNovaScotia

A year ago today we met this beautiful 17ft, 3,500lb Queen of the Ocean Nukumi! She’s the largest animal we’ve been able to sample, tag & release in our NW Atlantic White Shark Study. Her size & scars help tell inspiring stories of her decades helping balance our oceans.

Shark number 9 of #ExpeditionNovaScotia just swam off the lift and he was big! The fishing team says he's one of the toughest sharks they’ve ever brought back to the cradle. A tough shark deserves a tough name so say hello to Ironbound! He was also tagged by West Ironbound Island

A few days ago, 35 mi. W. of Tampa, Florida boaters had a unique #WhiteShark encounter. Spotting this #GreatWhiteShark in the #GulfofMexico doesn’t surprise our science team, since in recent days we’ve seen a great deal of activity there on the #OCEARCH Global Shark Tracker.

1,701 pd “Mahone” is the largest male #whiteshark #OCEARCH has worked up in the NW Atlantic #greatwhiteshark study. Named for #MahoneBay & French for a vessel commonly used in piracy, the bay has a rich history of hiding pirate ships. What new data could Mahone also be hiding?

The 4th white shark of #ExpeditionNovaScotia just safely swam off the lift! To our surprise after 3 adults in a row, she was a small 8’ 8” female. The people from Cape Breton call themselves Capers and so we are naming this shark Caper.

Right now the waters off North Carolina, South Carolina, Georgia & Florida are full of large white sharks. It’s a trend we’ve observed for years during this time period and now we’re calling this zone the North Atlantic Shared Foraging Area (NASFA). More bit.ly/2D2yRHy

Today we met #whiteshark Maple. She had a distinctive wound on the left side of her body & after initial assessment our science team believes it was likely due to a recent interaction with another larger, white shark. This interaction was possibly an example of dominance behavior

A strong name for a shark with a strong attitude. Say hello to white shark Ironbound. He’s named both for his toughness and because he was tagged near West Ironbound Island. He’s the 9th shark of #ExpeditionNovaScotia and the 2nd we got a semen sample from.
