In this paper, we present a novel Kalman filter approach to combine a hydrodynamic model-derived lowest astronomical tide (LAT) surface with tide gauge record-derived LAT values. In the approach, tidal water levels are assimilated into the model. As such, the combination is guided by the model physics. When validating the obtained “Kalman-filtered LAT realization” at all tide gauges, we obtaine...

Clams of the species Donax variabilis migrate shoreward during rising tides and seaward during falling tides. These clams spend most of the time in the sand, emerging several times per tidal cycle to ride waves. Migration is not merely a passive result of waves eroding clams out of the sand; rather clams actively jump out of the sand and ride specific waves. Such active migration is experimenta...

Intertidal macroalgae endure light, desiccation, and temperature variation associated with sub-merged and emerged conditions on a daily basis. Physiological stresses exist over the course of the entire tidal cycle, and physiological differences in response to these stresses likely contribute to spatial separation of species along the shore. For example, marine species that have a high stress to...

Pricing Prototypical Products When we think of colas, Coca-Cola first comes to mind. Products such as Cola-Cola, Tide laundry detergent and Chapstick lip balm are the prototypical products in their respective categories. Over three decades, research in consumer psychology has accumulated evidence on how prototypicality structures memory, shapes the composition of consideration set and influence...

Continuous monitoring of the range stability is a pre-requisite for sea-level rise and other demanding applications in satellite altimetry. Range stability may be investigated by either absolute or relative calibration techniques. In this study relative calibration is undertaken through intercomparison against TOPEX/Poseidon and absolute calibration undertaken in the vicinity of 8 tide gauges a...

Seasonal changes of the Adriatic Sea level, obtained by analyses of monthly sea level data measured at the Split tide gauge station in 1958-2001, are reported. The data were correlated by multivariant analysis to (1) local meteorological data on air temperature, air pressure, and precipitation, collected at the Split station and data on winds obtained from ECMWF ERA40 Reanalysis fields and (2) ...

[1] During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic Doppler current profiler surveys revealed the variability of the intense internal tide on the northern edge of Georges Bank. The nature of the internal tide was modulated by episodic surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying the otherwise vertically well-mixed outer bank. The introductio...
