Rio Guilarte (GUIL) a relocatable aqautic site and is part of the NEON Altantic Neotropical 04 domain. GUIL is a 2nd order wadeable stream field site located in central Puerto Rico on the site of an older agricultural experimental station. The surrounding land has primary been used for growing coffee, oranges and limes. This is a rainforest area, with daily afternoon rains and frequent flooding. Bamboo and other thick vegetation line the riverbanks and the water level can change dramatically when the rains come through. Automated stream sensors, and meteorological stations collect data year round and NEON field scientists collect field observations of aquatic plants, animals, biogeochemistry and more. This site has one meteorological station located in the riparian area. The met station is outfitted with a subset of the same sensors used at terrestrial sites. Measurements include wind speed and direction, air temperature, barometric pressure, relative humidity, shortwave radiation, and PAR. This site has one phenocam near the stream. Six groundwater wells throughout the site collect specific conductivity, water tempertaure, and elevation of groundwater. Total data products collected at this site: 81
