Summary

The Bocas del Toro Field Station is located on Colon Island in Bocas del Toro province near the border with Costa Rica. To the east is the Caribbean Sea and to the west is a large enclosed bay containing extensive coral reefs and grassbeds surrounded by banana plantations, farms, and forests including extensive mangroves. The area is rapidly being developed for tourism.

Between 2002 and 2005, STRI recorded hourly values of oceanographic and meteorological data, including Solar Radiation, Rain, Ocean Temperature, Tide and Wind Speed. By mid-2005 STRI installed an automated weather station over the bay located to the west of the Field Station (9? 21' 02.96'' N, 82? 15' 28.27'' W), and since then it has been collecting oceanographic and meteorological data at 15 minute intervals.

On April of 2015, and in cooperation with the Smithsonian MarineGEO/Tannenbaum Marine Observations Network (marinegeo.si.edu), a multi-sensor YSI Exo 2 Sonde (www.ysi.com/EXO2) was installed on the platform. This sensor records the following parameters every 5 minutes:

  1. Algae fluorescence (Falgae)
  2. Chlorophyll Fluorescence (Fchlorophyll)
  3. Chlorophyll Mass (Mchlorophyll)
  4. Conductivity (Cond)
  5. Specific Conductivity (Sp Cond)
  6. Fluorescent Dissolved Organic Matter (Fdom)
  7. Dissolved Oxygen, uncorrected (ODO)
  8. Dissolved Oxygen, corrected for temperature & pressure (ODO Sat)
  9. pH
  10. Quinine Sulfate surrogate for Fdom (QSefdom)
  11. Salinity
  12. Total Dissolved Solids (TDS)
  13. Turbidity
  14. Water Depth
  15. Pressure
  16. Water temperature

In addition, the program also collects seawater salinity and transparency (Secchi depth).

Bocas Biological Censuses
bci

In 1999, STRI initiated a mangrove, seagrass and coral censuses as part of the Caribbean Coastal Marine Productivity (CARICOMP) program. CARICOMP was a network of marine laboratories, parks, and reserves in 13 islands and 9 mainland countries throughout the Caribbean basin. Member laboratories monitored physical parameters, coral reefs, mangroves, and grassbeds using a common protocol to provide data for long-term comparative studies of biodiversity and productivity in Caribbean coastal ecosystems. While CARICOMP no longer exists, the censuses continue.

STRI monitors three sites (coral, reef, and mangrove) using the Level 1 protocols in the Methods Manual near the main laboratory in Bocas del Toro (See map).

Global Position System Station (Station Identifier = CN20)
bci

In collaboration with UNAVCO, a permanent Trimble NETR9 GPS station was installed at the Bocas Marine Station in August of 2013. This station now forms part of COCONet. Data from this station are automatically transmitted by satellite to a central server and can be accessed at this Nevada Geodetic Laboratory web site. More information about that station can be found here: http://pbo.unavco.org/station/overview/CN20

Please read our data use policy before using any data from this page.
