“…Second, NCEP winds derived from mostly land‐based observations also underestimate winds observed offshore. A corollary to these findings is that coastal ocean circulation models that are driven with wind fields that have been underestimated, will underestimate the coastal ocean circulation, as was shown for the WFS by comparing modeled and observed velocity vector time series at specific observing sites [e.g., Zheng and Weisberg , ; Weisberg et al ., ]. Remedies for underestimating the coastal ocean circulation response to wind forcing include adjusting the wind field a priori, as demonstrated by He et al .…”

Wind fields on the West Florida Continental Shelf are investigated using observations from five University of South Florida Coastal Ocean Monitoring and Prediction System buoys and seven of NOAA's National Ocean Service and National Weather Service, National Data Buoy Center stations or buoys spanning the 10 year period, 2004–2013. These observations are compared with NOAA's National Center for Environmental Prediction (NCEP) reanalysis wind fields (NCEP winds). The analyses consist of vector correlations in both the time and frequency domains. The primary findings are that winds observed on and near the coastline underestimate those observed offshore and that NCEP winds derived from assimilating mostly land‐based observations also underestimate winds observed offshore. With regard to wind stress, and depending upon location, wind stress derived from NCEP winds are 6%–49% lower than what is computed from observations over open water. A corollary is that wind forcing fields that are underestimated may result in coastal ocean model circulation fields that are also underestimated. These analyses stress the importance of having offshore wind observations, and suggest that adding more offshore wind observations will lead to improved coastal ocean wind fields and hence to improved model renditions of coastal ocean model circulation and related water property fields.

“…By nesting FVCOM in GOM-HYCOM, we downscale from the deep ocean, across the continental shelf and into the estuaries. Zheng and Weisberg (2012) provided a WFCOM proof of concept, and subsequent applications include gag grouper recruitment (Weisberg, Zheng & Peebles, 2014), K. brevis red tide (Weisberg, Zheng, Liu, et al, 2014;Weisberg, Zheng, Liu, Corcoran, et al, 2016) and tracking of the Deepwater Horizon oil spill (Weisberg, Zheng, Liu, Murawski, et al, 2016;Weisberg et al, 2017).…”

The Coastal Ocean Circulation Influence on the 2018 West Florida Shelf K. brevis Red Tide Bloom

et al. 2019

Blooms of the harmful alga, Karenia brevis on the west Florida continental shelf are thought to initiate offshore before manifesting as a nuisance along the coastline. Contributing to such blooms are a complex sequence of events occurring within oligotrophic waters, which in any given year may or may not be facilitated by the ocean circulation. Once initiation occurs, the delivery from the region of offshore origination to the region of coastline manifestation requires an upwelling circulation, whereby K. brevis cells are advected shoreward along the bottom. The 2018 K. brevis bloom was particularly intense owing to cells from the preceding 2017 bloom being reinforced by a newly formed bloom in 2018, a year when the offshore conditions in spring through early summer were again favorable for bloom development. As an event response to determine the potential for new cells to be delivered to the shore, a glider was deployed from 24 August 2018 to 17 September 2018 with a track line designed to map water properties over the hypothesized initiation region. The coastal ocean circulation during the deployment interval was generally upwelling favorable, but the passage of Tropical Storm Gordon temporarily disrupted this flow, after which K. brevis appeared along the Florida Panhandle coast. Strong upwelling then reestablished and K. brevis was subsequently observed along Florida's east coast. We describe the glider deployment, the K. brevis observations, and we use a numerical circulation model to account for the K. brevis manifestation as occurred along Florida's west, Panhandle, and east coasts.

“…appear to be more general in their spawning habitat than taxa that were encountered in large numbers at relatively few locations (e.g., K. pelamis and rough scad, Trachurus lathami). Higher levels of spawning-habitat selectivity may relate to the geography of egg and larval transport (Cowen & Sponaugle, 2009;Weisberg et al, 2014) or to orientation with dynamic physical processes that support biological productivity (Peebles, 2002;Peebles, Hall, & Tolley, 1996;Reglero, Tittensor, Alvarez-Berastegui, Aparicio-Gonzalez, & Worm, 2014).…”

“…The literature supporting dispersion‐based reproductive success is described by Karnauskas, Cherubin, and Paris (), who challenged this idea after their hydrodynamic models indicated predominant particle trajectories resulted in retention on the continental shelf, rather than offshore dispersion. Various other studies have also described biophysical interactions that retain the eggs and larvae of continental shelf (neritic) species on the continental shelf or near the upper slope (Hutchings et al., ; Muhling et al., ; Weisberg, Zheng, & Peebles, ). It thus appears that while some species have eggs and larvae that are widely dispersed in both neritic and deep‐oceanic waters, other species have eggs and larvae that are generally retained either in the deep sea or on the continental shelf, inclusive of the upper slope.…”

We combined research‐vessel cruises of opportunity with DNA barcoding to survey planktonic, percomorph fish eggs at 40 stations distributed across and around the Gulf of Mexico (GoM). The objectives were (a) to determine whether eggs of fishes that are potential candidates for the daily egg production method (DEPM) can be readily barcoded, (b) to identify taxa that are spawning in the GoM, (c) to determine encounter rates for eggs of economically valuable taxa, and (d) to characterize individual egg taxa as being primarily neritic, primarily oceanic, or primarily mixed (i.e., both neritic and oceanic). Of the 1,144 eggs that were individually barcoded, 709 (62%) were definitively identified to species (62 species from 42 families), with an additional 20 taxa identified to genus or subfamily level. The eggs of 15 economically important species were identified, most of which had intermediate encounter rates and moderately dispersed spatial distributions, as indicated by an index of aggregation. SIMPROF analysis of stationwise cluster analysis identified eight significant groups within the 35 stations that yielded percomorph eggs; a corresponding specieswise analysis identified six groups of stations as having a neritic egg community and two groups as having an oceanic community, with a community transition located at the shelf break. Although the neritic and oceanic stations did not share important species, it remains possible that coastal pelagic species have mixed neritic–oceanic distributions. Together, these results indicate DEPM fish‐egg surveys based on DNA barcoding are feasible at the large marine ecosystem scale.
