Estimates of high tide flooding on roadways within urban areas along the United States Atlantic coast
<p>Estimates of high tide flooding (HTF) on roadways in urban areas along the US Atlantic Coast. These estimates were calculated using NOAA HTF areal extent estimates, OpenStreetMap roadway data, and 2010 census-designated urban area and census block data. See the corresponding manuscript (Gold et al., 2021 - link coming soon) and <a href="https://github.com/acgold/HTF-on-roads">GitHub repository</a> for additional information about these data.</p>
Thermosphere Hough Mode Extensions (HMEs) for Solar Tides in Earth's Atmosphere
<p>The scientific basis for the atmospheric solar tide HME files contained here is described in Forbes et al. (2022). The directory "HME2022-Hough-UV functions-Tides" contains solutions to Laplace's Tidal Equation for the eastward(westward) propagating diurnal tides with zonal wavenumbers s = -1, -2, -3(+1, +2); the eastward(westward) propagating semidiurnal tides with zonal wavenumbers s = -1, -2, -3(+1, +2, +3, +4, +6); the zonally-symmetric (s = 0) diurnal and semidiurnal tides; and the westward-propagating terdiurnal tide with s = +3. In a widely-used abbreviated notation, these are, respectively: DE1, DE2, DE3, DW1, DW2; SE1, SE2, SE3, SW1, SW2, SW3, SW4, SW6; D0, S0; and TW3. These tides correspond to those measured in Earth's mesosphere and thermosphere. The directory "HME2022-output files-Tides" provides the amplitudes and phases (UT hour of maximum at 0 longitude) of eastward, southward, and vertical winds (m/s), temperatures (K), density perturbations relative to mean, and geopotential height (m) as a function of height (z, every ~4 km) and latitude (deg, every 3 deg), corresponding to several (2 to 7) HMEs for each of the aforementioned tides. Generally the number of HMEs corresponding to each tide is determined by the vertical wavelength Lz of each HME; HMEs with Lz < 30 km are excluded due to their inability to effectively penetrate into the thermosphere above 100 km altitude. The directory "HME_Legacy output files-Tides" includes a prior version of these HMEs that were used in several papers in the literature, but not publicly distributed. The data for each HME extend from pole to pole and from 0 to 400 km altitude. Each directory contains a README file containing further information on the data files.</p>

Blue crab, Callinectes sapidus, density and size in a salt marsh at low tide on the Coast of Virginia, Sept. 2021
While deconstructing a caging experiment at low tide in September 2021, researchers (Serina Wittyngham, Leah Scott, Andrew Nemeth, Emily Goetz, Esther Harper-Smith, David Johnson, and Cora Johnston) noticed blue crabs, Callinectes sapidus, ambushing fiddler crabs, Minuca (=Uca) pugnax, and purple marsh crabs, Sesarma reticulatum, from small, muddy pits in the marsh in Painter, Virginia, at low tide. On 28 Sept 2021, David returned to the marsh to estimate blue-crab density in the tall-form Spartina alterniflora (low marsh), the Sesarma-denuded zones and the short-form S. alterniflora (high marsh) zones by haphazardly tossing 15 1-m2 quadrats along a 200 m transect that crossed 6 creekheads. He also measured carapace width and the corresponding pit width and depth in which the crabs were found for up to 15 hapazardly encountered crabs in each of these zones (only 1 found in SSA). Sex was also noted. Surveys were conducted at low tide.

Swim with the tide: tactics to maximise prey detection by a specialist predator, the greater sea snake (Hydrophis major)
<p><span><span><span><span><span><span><span><span><span><span><span>The fitness of a predator depends upon its ability to locate and capture prey; and thus, increasing dietary specialization should favor the evolution of species-specific foraging tactics tuned to <span><span>taxon</span></span>-specific habitats and cues. Within marine environments, prey detectability (e.g., via visual or chemical cues) is affected by environmental conditions (e.g., water clarity and tidal flow), such that specialist predators would be expected to synchronize their foraging activity with cyclic variation in such conditions. In the present study, we combined behavioral-ecology experiments on captive sea snakes and their prey (catfish) with acoustic tracking of free-ranging sea snakes, to explore the use of waterborne chemical cues in this predator-prey interaction. In coral-reef ecosystems of New Caledonia, the greater sea snake (<i>Hydrophis major</i>) feeds only upon striped eel catfish (<i>Plotosus lineatus</i>). Captive snakes became more active after exposure to waterborne chemical cues from catfish, whereas catfish did not avoid <span><span>chemical</span></span> cues from snakes. Movement patterns of tracked snakes showed that individuals were most active on a rapidly falling tide, which is the time when <span><span>chemical</span></span> cues from hidden catfish are <span><span>likely to be</span></span> most readily available to a foraging predator. By synchronizing foraging effort with the tidal cycle, greater sea snakes may be able to exploit the availability of chemical cues during a rapidly falling tide to maximize efficiency in locating and capturing prey. </span></span></span></span></span></span></span></span></span></span></span></p>
