“…Studies have observed elevated concentrations of sulfide at bottom waters (1.6–3.5 mmol L -1 ) [ 32 ] and in porewaters (0.024–3.2 mmol L -1 ) [ 37 ] throughout the year. High sulfate reduction rates in BB (34.06 mmol L -1 h -1 ) relative to an oceanic station located ca.…”

“…The BB station (17.972 o N, 67.014 o W) is within The Bioluminescent Bay ( Fig 2 ), 3.2 km east of La Parguera town ( Fig 1 ). The Bioluminescent Bay has a 0.19 km 2 surface area, an average depth of 3.5 m [ 31 ], and a maximum of 4.5 m [ 32 ]. A 25-meter-wide red mangrove ( Rhizophora mangle L.) fringe surrounds the bay and is a significant organic carbon source.…”

“…The BB water column’s net community production has been reported to range from -5.99 to -2.49 g C m -2 day -1 [ 34 , 35 ]. The bathymetry has an irregular shape with a narrow and shallow outlet to nearby shelf waters and a sill (1 m depth) at the entrance, limiting exchange with outer waters and shelters from wave energy [ 32 , 36 ]. Most of the bottom comprises muddy sediments (ca.…”

Carbonate chemistry seasonality in a tropical mangrove lagoon in La Parguera, Puerto Rico

We investigated the seasonal carbonate chemistry variability within a semi-enclosed tropical mangrove lagoon in southwestern Puerto Rico. Biweekly measurements of seawater temperature, salinity, total alkalinity (TA), and dissolved inorganic carbon (DIC) were conducted from 2014 to 2018. We describe the possible mechanisms driving the observed variability by correlating the DIC/TA ratio with pH and Ωarg, suggesting that the mean pH (7.87 ± 0.09) and aragonite saturation state (Ωarg, 2.96 ± 0.47) of the mangrove lagoon negatively affected calcification. The measured pCO2 and DIC/TA ratios indicate that heterotrophic activity was the primary driver for persistent acidification, which reached its maximum expression during the wet season. We conclude that mangrove lagoons with limited seawater exchange and high carbon input will not mitigate ocean acidification.

“…Species richness and density can also decline where extreme salinities are prominent (Bayly, 1972;Vega-Cendejas and Hernández de Santillana, 2004). Increases in the concentration of salts may result in the dehydration of cells, and the inability to hypoosmotically regulate leading to a decrease of turgor pressure and mortality, especially in larvae, eggs and juveniles (Cintron, 1970;Aladin, 1991;Einav et al, 2002;Young and Potter, 2002).…”

With seawater desalination expanding rapidly, it is important that ecological studies are undertaken to determine the effects of brine discharge on the marine species in the area. The abundance of giant Australian cuttlefish (Sepia apama, Gray 1849) eggs and environmental data were recorded at nine sites near Point Lowly, Spencer Gulf, South Australia, an area where the largest desalination plant in the Southern hemisphere is proposed. In addition, the effects of different concentrations of desalination brine on the growth, survival and condition of cuttlefish embryos were investigated. The primary egg-laying sites for the cuttlefish were in the vicinity of Stony Point (sites 4 and 3) and the area with the least egg abundance was on the eastern and western areas around Point Lowly (sites 9 and 7) where no eggs were found. The survival of embryos decreased with an increase in salinity, with no embryos surviving to full term in salinities greater than 50 per thousand. Mean weight and mantle length also decreased with increasing salinity. Besides elevated salinity, the brine also had increased concentrations of Ba, Ca, K, Sr and Mg relative to water near Point Lowly. Brine discharge from seawater desalination poses a potential threat to the unique spawning aggregation of the giant Australian cuttlefish, in the upper Spencer Gulf, South Australia.
