Abstract Accelerated sea level rise was observed along the U.S. eastern seaboard south of Cape Hatteras during 2010–2015 with rates 5 times larger than global average for same time period. Simultaneously, levels decreased rapidly north Hatteras. In this study, we show that accelerated recorded between Key West and predominantly caused by a ~1 °C (0.2 °C/year) warming Florida Current linked to large‐scale changes in Atlantic Warm Pool. We also decline an increase atmospheric pressure combined...
Abstract During October 2014, Hurricane Gonzalo traveled within 85 km from the location of an underwater glider situated north Puerto Rico. Observations collected before, during, and after passage this hurricane were analyzed to improve our understanding upper ocean response winds. The main finding in study is that salinity potentially played important role on changes observed ocean; a near‐surface barrier layer likely suppressed hurricane‐induced cooling, leading smaller than expected...
The first eXpendable BathyThermographs (XBTs) were deployed in the 1960s North Atlantic Ocean. In 1967 XBTs operational mode to provide a continuous record of temperature profile data along repeated transects, now known as Global XBT Network. current network is designed monitor ocean circulation and boundary variability, basin-wide trans-basin heat transport, global regional content. ability Network systematically map upper thermal field multiple basins with sections at eddy-resolving scales...
Abstract The low‐amplitude, large‐scale, interannual, and longer‐term sea level changes are linked to the variations of ocean heat freshwater content strongly controlled by dynamics. Near coast, especially in low‐lying flood‐vulnerable regions, these can provide background conditions favorable for occurrence extreme levels that represent a threat coastal communities ecosystems. In this study, we identify tripole mode gyre‐scale surface height variability North Atlantic show is responsible...
Abstract The Gulf of Mexico ( GOM ) is the primary spawning ground for western Atlantic bluefin tuna (Thunnus thynnus) . In this work, information reported by previous studies about preferred environmental conditions occurrence larvae in integrated into a dimensionless index, BFT _Index. This index used to evaluate spatial and temporal variability areas with favorable within during 1993–2011. main findings work are that: (i) proposed successfully captures situ larvae; (ii) exhibit...
Over the past decade, measurements from climate-oriented ocean observing system have been key to advancing understanding of extreme weather events that originate and intensify over ocean, such as tropical cyclones (TCs) extratropical bomb (ECs). In order foster further advancements predict better understand these events, a need for dedicated component specifically support studies forecasts TCs ECs has identified, but not yet implemented. New technologies, pilot networks, targeted deployments...
Abstract The seasonal variability of the Florida Current (FC) transport is often characterized by presence an average annual cycle (8% variance) ∼3 Sv range peaking in boreal summer. However, seasonality displayed FC any individual year may have very distinct characteristics. In this study, analysis focuses on changes (73–525 day frequency band) that are associated with a variable phase, which defined as transient component (FCt, 27% variance). It shown FCt largely modulated westward...
Abstract Hurricane Michael formed on October 7, 2018, in the Northwestern Caribbean Sea, and quickly traveled northward through Gulf of Mexico, making landfall Florida panhandle as a devastating Category 5 hurricane only 3 days later. Before landfall, underwent rapid intensification, despite unfavorable atmospheric conditions. Using observations, we characterized key ocean features encountered by along its track, which are known for favoring intensification: high sea surface temperatures,...

Abstract The initialization of ocean conditions is essential to coupled tropical cyclone (TC) forecasts. This study investigates the impact observation assimilation, particularly underwater glider data, on high-resolution TC Using Hurricane Weather Research and Forecasting (HWRF) Model–Hybrid Coordinate Ocean Model (HYCOM) system, numerical experiments are performed by assimilating observations alone with other standard for forecast Gonzalo (2014). able provide valuable information...
Abstract The nearly four‐decades‐long quasi‐continuous daily measurements of the Florida Current (FC) volume transport with a submarine cable at about 27°N represents longest climate record boundary current in existence. Given extremely high utility this time series for monitoring Atlantic meridional overturning circulation, as well improving understanding and prediction regional weather, phenomena, coastal sea‐level, ecosystem dynamics, efforts are underway to establish suitable backup...
Abstract The meridional overturning circulation (MOC) is a major driver in global redistribution of heat, which modulates climate and weather. Altimeter sea surface height measurements situ hydrographic data are combined this work to derive monthly synthetic temperature salinity (T/S) profiles along zonal transbasin sections both the North (26.5°N) South (20°S, 25°S, 30°S, 35°S) Atlantic Ocean since 1993, then used estimate MOC heat transport (MHT). Consistent with previous studies, results...

To accomplish this, situ satellite‐derived observations are used 1993 2010. main finding that meridional changes westerlies with Southern Annular Mode (SAM) drive anomalies Ekman layer Subantarctic Front (SAF) Polar (APF)...
Abstract Major Atlantic hurricanes Irma, Jose, and Maria of 2017 reached their peak intensity in September while traveling over the tropical North Ocean Caribbean Sea, where both atmospheric ocean conditions were favorable for intensification. In situ satellite observations revealed that these areas exhibited (i) sea surface temperatures above 28°C, (ii) upper-ocean heat content 60 kJ cm −2 , (iii) presence low-salinity barrier layers associated with a larger-than-usual extension Amazon...
Abstract In this study, mechanisms causing year-to-year changes in the Florida Current seasonality are investigated using controlled realistic numerical experiments designed to isolate western boundary responses westward-propagating open ocean signals. The reveal two distinct processes by which signals can modulate phase of variability, we refer as “direct” and “indirect” response mechanisms. direct mechanism involves a two-stage anticyclonic eddies characterized influence Rossby wave...
As communities grapple with rising seas and more frequent flooding events, they need improved projections of future rise over multiple time horizons to assist in a multitude planning efforts. There are currently few different tools available that can use plan including the Sea Level Report Card products generated by U.S. Federal interagency task force on sea level rise. These start, but it is recognized not necessarily enough at present give types information needed for decision support,...
