“…This situation, coupled with the effects of climate change, can contribute to the deterioration of water quality and the increased vulnerability of the surrounding ecosystems [5]. The dynamic component of marine ecosystems is subject to natural variability that occurs on different temporal and spatial scales, which interact with the biological cycles of the species [6]. Environmental changes can affect marine life, which depends on the amount of available food and primary production.…”

In recent years, the northwestern part of the North Pacific areas of Costa Rica has undergone rapid socioeconomic development. This situation, combined with the scarce available information about the water quality of the Gulf of Papagayo, became the starting point to carry out a study to investigate the spatiotemporal variations of physicochemical and biological parameters of surface waters. Seven samplings were collected during the dry season and the rainy season from October 2016 to February 2018. Water quality parameters such as: temperature, salinity, dissolved oxygen, and chlorophyll a of six analytes: nitrate, nitrite, ammonia, phosphate, silicate and biological oxygen demand were measured. The results showed that phosphate and ammonium levels were lower during the rainy season (<6 µg P-PO4−3 L−1–9.53 µg P-PO4−3 L−1 and <11 µg N-NH4+ L−1–9.57 µg N-NH4+ L−1) than during the dry season (<6 µg P-PO4−3 L−1–13.64 µg P-PO4−3 L−1 and <11 µg N-NH4+ L−1–14.43 µg N-NH4+ L−1), which may be related to low rainfall (0, 00–26, 16 mm) during the sampling period. The dry season showed enrichment of ammonium, phosphate, and chlorophyll a due to the influence of the coastal upwelling for the intensification of the Papagayo winds from December to March. The physical, chemical, and biological indicators demonstrated that the Gulf waters had adequate quality. Nonetheless, there are specific areas such as Culebra Bay with conditions that could show deterioration of water quality.

“…Environmental changes can affect marine life, which depends on the amount of available food and primary production. Ecosystems can be easily altered, without appreciating the damage at first glance, due to the direct and indirect entry of polluting substances, such as nutrients that can limit or increase the production of an ecosystem [6].…”
