Culturing Vallisneria americana for Restoration Efforts
… phosphorous release into the water column from sediments. There was a significant difference in the amount of phosphorous released if commercial sediment was used with a low iron amendment or without an iron amendment. The second study consisted of planting V. americana on two different sediment …

The Fate and Mobility of Heavy Metals in East Anglian Salt Marsh Sediments
… in Earth Sciences. Geochemical proxies in sedimentary rocks used to reconstruct past redox conditions—such as the speciation of iron mineralogy, δ98Mo, and δ53Cr—rely on the assumption that the geochemical signature acquired at the sediment surface is translated directly into the geologic …

Assessment of road pollutants in roadside retention ponds.
… urban drainage systems (SuDS) such as retention ponds manage runoff and are a key pathway for pollutants from roads to the wider aquatic environment. Hence the aim of this work was to assess retention ponds as a pathway for TRWPs, MPs, and additive chemicals entering the aquatic environment. A …

Life history of a native emydid turtle (Malaclemys terrapin centrata) on the remote oceanic islands of Bermuda
… presently inhabit only four small brackish water ponds on a private golf course. The life history of this species is poorly understood on Bermuda and so the aim of this study was to fill these knowledge gaps, to compare the results with what is known from other areas in the North American range, …

Quaternary geology of Rolette County, North Dakota
… Basic lithologies recognized in the surface sediments were bedded clay, silt, sand, and gravel; and three types of non-bedded diamicton. These were combined and, with bedding characteristics and organic content, formed 15 practical field mapping units. Geologically significant scarps and hill …
