Hanken, James 1975 Journal Green Turtle Station sea level, Tortuguero, Limón Province, Costa Rica 9 July Left NYC by plane 1 July and arrived San José via Miami and Grand Cayman Is. that night. Stayed overnight in S at the Tela Inn where I looked up with Chuck Carr and Kathy Landauer who had come up from Tortuguero to renew visas. We remained in San José until the 4 July buying supplies (I also obtained a collection permit from the Ministerio de Agricultura y Ganadería). We flew to Limón the next morning, 4 July, and took a boat up to Tortuguero the following morning (5 July). The beginning of the regular turtle tagging program still awaits arrival of Steven Carr from Florida who is bringing more gear and another tagger. This week I've been busy with maintenance work around the camp station getting things in working order. Also, with the help of Reto Martiney and Alonso Rankin did egg collecting (see add) for Bill Vaneyn. Hopefully we can finish this week so that tagging begins. The only potentially difficult task will be obtaining the samples of blood serum. The villagers are taking ~3 turtles/week but it is next to impossible to find out, in
