- Abstract:
-
Marine turtles on the nesting beaches of La Flor public beach (latitude11.14282, longitude 11.14282, geographic datum WGS84), Pacific Nicaragua, and Pacuare Reserve public beach (latitude 10.20123, longitude 83.25925) and Tortuguero (latitude 10.59583, longitude 83.52520) , Caribbean, Costa Rica were observed during late hours after sunset. Observations where noninvasive, geo-referenced and observers stayed three meters away from the sea turtles, according to the national requirements (no light, and some limited red light was used for field clarifications). Many surrounding attributes were taken into consideration and measured including date, time, species, location, observed cysts present in the facial region, visually estimated carapace length, other disturbances present on the beach, number of people/tourists and dogs present, plastic encountered, and if applicable, start and end time of specific activities of nesting (such as start of nest time, start of egg laying and start of Ridley dance.) These data are part of a citizen science project and from a sea turtle fieldclass with Maderas Rainforest Conservancy. This dataset consists of an MS Excel sheet and is less than 1MB in size. Some photoes were taken to present the beaches and procedures.
- Purpose:
-
To observe and record non-invasive data of nesting sea turtles on the public beach of La Flor beach (Pacific) in Nicaragua and Pacuare Reserve and Turtuguero (Caribbean), Costa Rica.

La Flor is a public beach located in southwest Nicaragua. It is a narrow and curved beach of 1.5km length that has high rock cliffs at either end. The beach is mostly sandy, but has one edge with pebbles and rocks. Right at the beach edge is a forest that then leads to a camping ground with a ranger station.
Pacuar Reserve hosts Playa Vigilada which is 6km in length with a station located on the south end and an additional station located in the north. A tropical forest lines the shore of the beach with a brackish river running on the other side of the forest which leads into the ocean.
Tortuguero is a public sand beach and we surveyed 1.75km.

- Methodology_Description:
-
We walked on the public beach, usually with a guide
or tourists. When turtle was found, e.g. nesting,
we followed usual procedures and colleted all data
as specified. This survey is opportunistic and covers
usually the time 7PM til 2AM.
Some photos were taken of the habitat and situation once the turtle was done with nesting or gone.
