(oceanography)
The benthic region extending from mean low water (2-3 fathoms or 40-60 meters, according to some authorities) to a depth of about 110 fathoms (200 meters), or the edge of a continental shelf, beyond which most abundant attached plants do not grow.

In turn, a number of environmental parameters that are influenced by restoration designs, including available subtidal habitat, tidal flow, vegetation cover, microhabitat (used here as a small scale environmental feature, such as an eelgrass bed or mudflat, within the larger estuary habitat) diversity, and average depth, vary greatly among sites, and can impact ecological function (Zedler 1996; Nicolas et al.
Finally, this work provides the basis of the influence of sedimentation in subtidal algal assemblages in Zihuatanejo.
In a summary of his field notes, Kendrick (1988a) describes diverse macroalgal communities restricted to lower intertidal and upper subtidal (2-3 m) depths in the Western region, and best developed in exposed locations.
Fish were captured in a boat-deployed bag seine in subtidal and intertidal waters (depths [less than or equal to] 10 m) during the summers of 2010 and 2012.
The timing of brooding and recruitment within a particular habitat can clearly vary, and these results suggest that brooding studies at higher latitudes or subtidal locations should start quantifying reproductive activity by early-to-mid April when the DMWT is approaching 10[degrees]C.
The typical degree of wave action was also statistically significantly associated with the ENT concentration in the subtidal and intertidal zones, but not in the supratidal zone (Table 3).
The time of larval release by subtidal crustaceans is not random; it is related to diel and tidal cycles (reviewed by Forward, 1987; Morgan, 1995; Christy, 2011).
The calcareous sandstones of the formation formed in a very shallow subtidal environment close to the ancient coastline (Poldsaar & Ainsaar 2014).
Sea squirts such as these commonly grow on hard surfaces in shallow subtidal areas and are particularly prevalent in marinas.
Originally, they were reported to primarily occur in the middle and upper intertidal zone (Fukai, 1988; McDermott, 1992,1998); however, more recent studies have found them living in lower intertidal and subtidal habitats as well (Kraemer et al.
The purchase by the Conservation Fund for Texas secures vital habitat for migrating birds and will permanently protect estuarine emergent wetlands, associated tidal flats, subtidal ponds and Gulf coast beachfront, said Jim Suydam, spokesman for the Texas General Land Office.
More than 151,000 cubic yards of sediment will be dredged from the subtidal area and an additional 15,800 cubic yards will be excavated or dredged from the shoreline and intertidal area.
