“…If the stratigraphic records of these cores are conformable, the stratigraphic units directly underlying pool deposits indicate that pools form in low or high/low mixed salt marsh environments. These contacts may be erosional, however, as the result of sulfate reduction (van Huissteden and van de Plassche 1998) and/or destructive disturbances like ice plucking (Argow and Fitzgerald 2006) that remove material from the stratigraphic record. If this is the case, the records simply indicate that pool origin was secondary and do not inform us about the microenvironment in which they formed.…”

“…Earlier work focuses on salt pool genesis, specifically whether pools are primary features that begin on a tidal flat that later become surrounded by vegetation (Yapp et al 1917) or secondary features that result from disturbance to a vegetated marsh, including: enduring algal mats (Harshberger 1916), tidal wrack (Ranwell 1964), and/or snow patches (Chapman 1960); scour, plucking, and/or sediment deposition from ice (Argow and Fitzgerald 2006); inadequate drainage resulting in waterlogged substrate (Redfield 1972); insufficient sedimentation and/ or peat compaction (Redfield 1972); and intentional creation, e.g., from collapsed man-made ditches (Miller and Egler 1950). In coastal Louisiana, pool formation and enlargement are clearly contemporary processes that are directly linked to deltaic salt marsh fragmentation and breakup (Turner 1997;Day et al 2000).…”

Salt pools are water-filled depressions common to north-temperate salt marshes. In Wells, ME, USA, cores reveal a unique salt pool signature consisting of watersaturated dark-gray mud often containing fragments of Ruppia maritima. Cores through pool sediment reenter salt marsh peat, not tidal flat sediment, demonstrating that most pools are of secondary origin. A principal component analysis of attribute data collected from 119 pools defines three distinct pool types: those with (1) surrounding highmarsh vegetation and thick heavily undercut banks (40% of the variance), (2) surrounding low-marsh vegetation and thicker slightly undercut banks (18% of the variance), and (3) surrounding low-marsh vegetation and less thick moderately undercut banks, containing R. maritima and a surficial drainage (15% of the variance). Cores and spatiotemporal analyses of aerial photographs between 1962 and 2003 reveal dramatic salt marsh surface dynamism suggesting that salt pools influence the geomorphological evolution of coastal marshes.

“…The tidal marshes and estuarine tributaries are frequently ice covered in winter, which has major impacts on biological, chemical, and sedimentological processes ( Fig. 2) (Meese et al, 1987;Argrow and FitzGerald, 2006). The mean annual precipitation is 1222.5 mm (48.13 in.…”

“…Salt marshes in Maine are often exposed to harsh New England winters when ice disturbance (e.g. rafting) can affect sediment deposition (Argow & Fitzgerald 2006), plant recolonization (Ewanchuk 2003) or inter-specific plant competition (Bertness & Ewanchuk 2002). Tidal ranges are also much greater (i.e.…”

Both permanent high marsh pools and the intertidal surfaces of Spartina patens high marshes in southern Maine, USA, proved to be important habitat for resident mummichog Fundulus heteroclitus production. Manipulations of fish movement onto high marsh surfaces revealed similar growth rates and production among fish that were (1) restricted to pools, (2) had access to known areas of marsh surface, or (3) had free access to the entire marsh. Smaller scale manipulations with marked fish revealed that males with access to the marsh surface accumulated significantly more biomass, often exhibited higher growth rates, and had a 1.6 × greater production rate than males restricted to pools. Female production was only slightly higher for fish that could access the marsh compared to fish restricted to pools. While both pools and marsh surface appeared to support fish production, habitat partitioning also existed between sexes of mummichogs; males may rely more on the marsh surface for food while females rely more on pools. Growth and production of mummichogs in pools on the high marsh surface was lower than values reported from more southern, low marsh dominated systems. This was attributed to differences in (1) abiotic factors of salt marsh pools (this study) and tidal creeks and channels (other studies), (2) climate, and (3) tidal inundation and access time to the marsh surface. Fish production on the surface of Gulf of Maine high marsh ecosystems was equivalent to production in adjacent tidal creeks and channels. Thus, the high marsh surface proved to be an important habitat for supporting fish production in this region.
