in relation to the history of the earth. Varves Glacial streams carry sediments, eroded by glaciers, to glacial lakes. In summer, thick layers of coarse-grained sediments are deposited, while in winter, thinner layers of fine-grained sediments are deposited. Year after year the sediments accumulate in this way.

Distribution of Sediments The sediment of continental shelves is called neritic sediment, and contains mostly terrigenous material. Sediments of the slope, rise, and deep-ocean floors are pelagic sediments

Shoreline and Shelf Sediments 1) Shallow marine sediments that deposit along shorelines and offshore shelf are termed neritic 2) Coast and shelf sediments are of two types: LandLand--derived inorganic rock and mineral derived inorganic rock and mineral fragments of gravel, sand, silt, and c

Sea Urchins and Sand DollarsSea Urchins and Sand Dollars Members of class Echinoidea. Movable spines are attached to its internal skeleton, which is formed by bony plates that are fused. Members are characterized by oval or round bodies that lack arms. Inhabit the intertidal and subtidal zonesInhabit the intertidal and subtidal zones . .

Early Pliocene sediments are found mainly in the Viking Graben area, whereas sediments with an Early Pleistocene age occur over the entire distribution area of the Utsira Formation. All sediments were deposited in neritic environments that gradually bec

These sediments are variably colored, unconsolidated to poorly consolidated, fine to coarse grained, clean to clayey, unfossiliferous sands, sandy clays and clays. Organic debris and disseminated organics may be present in these sediments. The undifferentiated Tertiary -Quaternary sediments are

monitoring of marine benthic habitats (Noble- James et al., 2017). Common Standards Monitoring: developed for site monitoring and assessment of protected sites (JNCC, 2004). Specific habitat guidance relevant to subtidal sediments: Inshore Sublittoral Sediment Habitats (JNCC, 2004a), Estuaries (JNCC, 2004b), Inlets & Bays (JNCC, 2004c).

Ground-truth basis for development of habitat map for the entire Oculina Bank region, based on analysis of multi-beam bathymetry, backscatter, and imagery using seabed classification software (QTC MultiView); habitat map to be completed by May 2007. ROV dives documented past recolonization experiments; new growth of Oculina corals on .

Offsite Vehicle Tracking: Several measures will be provided to help reduce the impact of vehicle tracking sediments. A stabilized construction entrance with trap rock and wood siding will be constructed at the entrance of each construction site to help reduce vehicle tracking of sediments, and maintained as necessary.

Wald and Graves, 1998; Stidham et al., 1999) has also dem-onstrated the importance of understanding basin amplifica-tion, which is paramount to obtaining an estimate of seismic hazard. The San Francisco Bay is a shallow sedimentary basin containing terrestrial and marine sediments of the Pli-

Rietveld Autoquan/BGMN software [9]. Determination of the Distribution Coefficient Sediments are composed of layered silicates and amor-phous substances characterized by specific sorption and ion exchange properties. These properties play an important role in water purifying processes by retention of many harmful substances in the sediments.
