Changes in meteorological parameters and seawater temperature in 5 m depth at Matapalo over 12 months.

<p>(a) Mean daily air temperature [°C] and daily precipitation [mm]. (b) Mean daily seawater temperature [°C] and mean daily wind speed [m s^-1]. Shaded area = upwelling period.</p

Changes in environmental parameters at Matapalo in a weekly resolution over 12 months.

<p>(a) Seawater temperature (weekly data points measured with MANTA loggers and daily averages calculated from continuous HOBO logger data) and salinity; (b) pH value (total scale) and concentration of dissolved oxygen; (c) concentrations of inorganic nutrients phosphate, ammonia and nitrate; (d) concentration of chlorophyll <i>a</i>; (e) concentrations of particulate organic nitrogen and carbon; (f) concentration of dissolved organic carbon. Error bars indicate ± SE. Shaded area = upwelling period.</p

Upwelling event at the Pacific coast of Costa Rica on 17 February 2014.

<p>Color scale in the water indicates sea surface temperature (SST). Shading on land indicates altitude; note the depression in the volcanic mountain range at Lake Nicaragua that enables Trade Wind crossing from the east. The inset shows the locations of study sites Matapalo (10°32’21”N, 85°45’59”W) and Bajo Rojo (10°57’26”N, 85°43’59”W). SST data were derived from a daily, global 1-km SST data set (GHRSST, Level 4, G1SST) produced by the JPL Regional Ocean Modeling System group [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142681#pone.0142681.ref019" target="_blank">19</a>], available at <a href="http://ourocean.jpl.nasa.gov/SST/" target="_blank">http://ourocean.jpl.nasa.gov/SST/</a> (accessed 09.12.2014). Data were visualized with the software Ocean Data View (Schlitzer, R., Ocean Data View, <a href="http://odv.awi.de/" target="_blank">http://odv.awi.de</a>, 2013).</p

Mean environmental parameters (± SE) at Bajo Rojo Reef in 10 m water depth during the three main seasonal periods.

<p>Variables were measured constantly (water temperature; daily averages), weekly for several hours (pH, salinity, dissolved O₂; sampling day average) or weekly in triplicate (nutrients and particulate as well as dissolved organic matter; sampling day average). The number of replicates for each parameter and season is displayed in brackets.</p><p>Mean environmental parameters (± SE) at Bajo Rojo Reef in 10 m water depth during the three main seasonal periods.</p
