Background Coral reefs are facing increasing pressure from natural and anthropogenic stressors that have already caused significant worldwide declines. In January 2010, coral of Florida, United States, were impacted by an extreme cold-water anomaly exposed corals to temperatures well below their reported thresholds (16°C), causing rapid mortality unprecedented in spatial extent severity. Methodology/Principal Findings Reef surveys conducted Martin County the Lower Florida Keys within weeks...
Starting in 2011, coastal areas of the Caribbean Sea and tropical Atlantic Ocean began to experience extraordinary yearly accumulations pelagic Sargassum brown alga. Historical reports place large quantities only North (mostly Gulf Mexico Sargasso Sea). Accumulations have continued. We used a numerical particle-tracking system, wind current reanalysis data, drifting buoy trajectories, satellite imagery determine origin that is now found persistently Atlantic. Our analyses suggest during...
Abstract. Measurements of dissolved organic carbon (DOC), nitrogen (DON), and phosphorus (DOP) concentrations are used to characterize the matter (DOM) pool important components biogeochemical cycling in coastal ocean. Here, we present first edition a global database (CoastDOM v1; available at https://doi.org/10.1594/PANGAEA.964012, Lønborg et al., 2023) compiling previously published unpublished measurements DOC, DON, DOP waters. These data complemented by hydrographic such as temperature...
The southern Caribbean Sea experiences strong coastal upwelling between December and April due to the seasonal strengthening of trade winds. A second was recently detected in southeastern during June–August, when local wind intensities weaken. Using synoptic satellite measurements situ data, this mid-year characterized terms surface subsurface temperature structures, its mechanisms were explored. lasts 6–9 weeks with sea (SST) ~1–2° C warmer than primary upwelling. Three possible analyzed:...

Abstract. The presented pilot for the Synthesis Product Ocean Time Series (SPOTS) includes data from 12 fixed ship-based time-series programs. related stations represent unique open-ocean and coastal marine environments within Atlantic Ocean, Pacific Mediterranean Sea, Nordic Seas, Caribbean Sea. focus of has been placed on biogeochemical essential ocean variables: dissolved oxygen, inorganic nutrients, carbon (pH, total alkalinity, carbon, partial pressure CO2), particulate matter, organic...
Abstract Dissolved organic carbon (DOC) in coastal waters is integral to biogeochemical cycling, but global and regional drivers of DOC are still uncertain. In this study we explored spatial temporal differences concentrations stocks across the ocean, how these relate temperature salinity. We estimated a median stock 3.15 Pg C (interquartile range (IQR) = 0.85 C), with being 2.2 times higher than open ocean surface waters. Globally seasonally, salinity was main driver correlated negatively...
Abstract An extreme Saharan dust storm (named Godzilla) arrived at the Caribbean region in June 2020, deteriorating air quality to hazardous levels and unhealthy conditions for sensitive groups of people. Our main objective was characterize populations risk by analyzing distribution events Puerto Rico, conducting an online survey assess community perceptions on health effects. Three daily satellite aerosols products from 2013 2020 were retrieved Visible Infrared Imaging Radiometer Suite over...
The Sardinella aurita fishery off northeastern Venezuela, region of seasonal wind-driven coastal-upwelling, accounts for 90% the Caribbean Sea small pelagic catch. This law-protected artisanal takes place up to ~10 km offshore. spatial distribution, number schools, and biomass S. were studied using eight hydro-acoustic surveys (1995–1998). study included analysis satellite-derived sea surface temperature chlorophyll-a. Surveys grouped by strong, weak, transitional upwelling seasons....
Enterococci concentration variability at Escambron Beach, San Juan, Puerto Rico, was examined in the context of environmental conditions observed during 2005-2015. Satellite-derived sea surface temperature (SST), turbidity, direct normal irradiance, and dew point were combined with local precipitation, winds, mean level (MSL) observations a stepwise multiple regression analyses (Akaike Information Criteria model selection). Precipitation, MSL, SST, turbidity explained 20% variation...

The Cariaco Basin, located on the continental margin of south-eastern Caribbean Sea, has been a site extensive oceanographic research since early 1950s. Here we examined seasonal and spatial variability in satellite wind, sea surface temperature (SST), chlorophyll (CHL), primary production (PP) within Basin (1994–2009). This implications modulating vertical flux particulate material to bottom basin. While cross-shore Ekman Transport was positive (upwelling inducing) year-round, it showed...
