A picture from when my host family and I went sailing on Wednesday night.
This was my fifth week here in Long Beach and it was definitely one of my favorite. On Monday, we took the boat out to find the receivers that hadn’t surfaced when it was supposed to. An engineer and two interns from the company Blue Robotics used their ROV to find them. Due to the strong current and bad underwater visibility, we retrieved one receiver out of four. On Tuesday, a graduate and I entered the data of all of the sharks tagged by the CSULB shark lab into a database so if a shark is detected near the Horizon Charters dive boat, it will alert the people on board and show information about the shark. On Wednesday, I helped measure jaws that were confiscated by U.S. Fish and Wildlife. These jaws were labeled by the fisherman as bull and tiger sharks but out of the approximately 6,000 jaws, there are a couple bull shark jaws and no tiger shark jaws. By measuring the jaw, you can learn approximate size and sexual maturity. You can also identify the sex by looking at it. On Thursday we went to Seal Beach to collect round stingrays for the Monterey Bay Aquarium and for one of the graduate’s research project. We used a 100m long net in which we caught and estimated 500 to 700 rays. On Friday, I continued to measure jaws and I helped the graduate with the quarantine for the rays, which they are in for 24 hours to kill parasites.

This weekend I went down to San Diego to visit Ty Kraft, another pinhead intern from Ridgway Secondary School.
