Japanese Loggerheads Released off of Kochi, Japan

Link to current trajectory map of #203 and #204 3/27/2024 Turtle 204 continues to transmit locations very reliably.  It has been transmitting for 208 days now and has traveled roughly 8000 km.  Given that 208 days represents 4992 hours, 204 has been traveling/swimming at a rate of approximately 1.6 km/hour.  Below is a short animation of the water currents and 204's track indicating where 204 is as of March 27, 2024.   2/29/2024 Turtle 203 stopped transmitting on 2/3/24 but 204 continues to transmit.  Below is the current location of 204.  It appears that 204 is riding around in a small current eddy that has branched off of the main Kuroshio current.  These eddys tend to concentrate food items and are know to be areas preferred by loggerheads.   Above is an animation of the travels of #204 in the Eddy shown above from 1/13/24 to 2/29/24.   2/2/2024 Here is an animation of  203's and 204's trajectories after their release in September until February 2, 2024.   12/11/2023 Whi

 SATURDAY / SUNDAY 11/19 AND 11/20/2022 Port of Nagoya Public Aquarium's Chelonia Institute. Saturday afternoon, after we checked in on the little tagged loggerhead and visited the aquarium, we departed for a short visit to Osu shopping street to wander around- take a little break from the "grind". Sunday: After checking out of the hotel, we caught a local train to Nagoya Station and then the Nozomi shinkansen to Shin Osaka where we were supposed to meet up with Takahashi Ishikara.  Unfortunaely, he was unable to make it because of an emergency at his aquarium.  Flight home.. We took the Haruka rapid train to Kansai and checked in without too much hastle.  Flight left on time and was about 1/2 full which gave everyone lots of room.   Arrived in HNL on time and GHB left for home while I remained to catch my flight to Kona 3 hours later. Flight to Kona was on time so the trip went very well from the beginning to the end. All in all, a whorl-wind visit that was very producti

 Saturday, 11/19.2022 Today is our final day in Nagoya.  We are headed to the aquarium to check on our "tagged" loggerhead and will spend some time with Kurita san and team to finalize all talking points. We will also take some time to walk around the aquarium and see the various exhibits before we leave our wonderful Japanese team mates for the time being.   This afternoon will be spent doing a little shopping and visit Osu district shopping street.  Below:  Walking to the Port of Nagoya Public Aquarium.... a beautiful day and a beautiful area.

THIRD DAY- Practice Attachment Day

Friday,  11/18/2022 Port of Nagoya Public Aquarium. Today we will conduct a practice attachment to one of cohort 1 juvenile loggerheads.  We will take some time to experiment with attachment materials to determine what we consider the best for attachment.   After some experimentation, we decided to stick with a UV activated polyester resin and fiberglass cloth. Masanori Mori picks a mid-sized turtle from cohort 1 to place a mock tag on. GHB and Saito san transporting our little loggerhead over to the work area. Mixing the elastomer base for the tag.
