Physicsof Estuariesand Coastal Seas
1 August 12-16 2012 n New York City The Physics of Estuaries and Coastal Seas Symposium 2 3 Assessing Suspended Sediment Dynamics in the San Francisco Bay-Delta System: Coupling Landsat Satellite Imagery, in situ Data and a Numerical Model Fernanda Achete1, Mick van der Wegen1, Dave Schoellhamer2, Bruce E. Jaffe2 1 UNESCO-IHE, Delft, Netherlands 2 U.S. Geological Survey Rivers draining the Central Valley and Sierras of California, including the Sacramento and San Joaquin Rivers, meet in the Delta before discharging into the northeastern end of the San Francisco Estuary. The Bay-Delta system is an important region for a) economic activities (ports, agriculture, and industry), b) human settling (the San Francisco Bay area hosts 7.15 million inhabitants) and c) ecosystems (the Delta area hosts several endemic species and is an important regional breeding and feeding environment). Human activities, including hydraulic mining and agriculture development have affected the Bay-Delta system over the past 150 years. Other examples of anthropogenic influence on the system are damming of rivers, channels dredging, land reclamation and levee construction. Suspended sediment concentration (SSC) has varied considerably as a result of these activities. The change in SSC has a high impact on ecosystems by influencing light penetration that is closely related to primary production, contaminants distribution and marshland development. Better understanding of the spatial distribution and temporal variation of SSC opens the way to improved understanding ecosystem dynamics in the Bay-Delta system and to assess the impact of future developments such as water export, sea level rise and decreasing SSC levels. -

Tide Simplified by Phil Clegg Sea Kayaking Anglesey
Tide Simplified By Phil Clegg Sea Kayaking Anglesey Tide is one of those areas that the more you learn about it, the more you realise you don’t know. As sea kayakers, and not necessarily scientists, we don’t have to know every detail but a simplified understanding can help us to understand and predict what we might expect to see when we are out on the water. In this article we look at the areas of tide you need to know about without having to look it up in a book. Causes of tides To understand tide is convenient to imagine the earth with an envelope of water all around it, spinning once every 24 hours on its north-south axis with the moon on a line parallel to the equator. Moon Gravity A B Earth Ocean C The tides are primarily caused by the gravitational attraction of the moon. Simplifying a bit, at point A the gravitational pull is the strongest causing a high tide, point B experiences a medium pull towards the moon, while point C has the weakest pull causing a second high tide. Because the earth spins once every 24 hours, at any location on its surface there are two high tides and two low tides a day. There are approximately six hours between high tide and low tide. One way of predicting the approximate time of high tide is to add 50 minutes to the high tide of the previous day. The sun has a similar but weaker gravitational effect on the tides. On average this is about 40 percent of that of the moon. -
Preparing for Tomorrow's High Tide
Preparing for Tomorrow’s High Tide Sea Level Rise Vulnerability Assessment for the State of Delaware July 2012 Other Documents in the Preparing for Tomorrow’s High Tide Series A Progress Report of the Delaware Sea Level Rise Advisory Committee (November 2011) A Mapping Appendix to the Delaware Sea Level Rise Vulnerability Assessment (July 2012) Preparing for Tomorrow’s High Tide Sea Level Rise Vulnerability Assessment for the State of Delaware Prepared for the Delaware Sea Level Rise Advisory Committee by the Delaware Coastal Programs of the Department of Natural Resources and Environmental Control i About This Document This Vulnerability Assessment was developed by members of Delaware’s Sea Level Rise Advisory Committee and by staff of the Delaware Coastal Programs section of the Department of Natural Resources and Environmental Control. It contains background information about sea level rise, methods used to determine vulnerability and a comprehensive accounting of the extent and impacts that sea level rise will have on 79 resources in the state. The information contained within this document and its appendices will be used by the Delaware Sea Level Rise Advisory Committee and other stakeholders to guide development of sea level rise adaptation strategies. Users of this document should carefully read the introductory materials and methods to understand the assumptions and trade-offs that have been made in order to describe and depict vulnerability information at a statewide scale. The Delaware Coastal Programs makes no warranty and promotes no other use of this document other than as a preliminary planning tool. This project was funded by the Delaware Department of Natural Resources and Environmental Control, in part, through a grant from the Delaware Coastal Programs with funding from the Offi ce of Ocean and Coastal Resource Management, National Oceanic and Atmospheric Administrations, under award number NA11NOS4190109. -
Principal Fortifications of the United States (1870–1875)
Principal Fortifications of the United States (1870–1875) uring the late 18th century and through much of the 19th century, army forts were constructed throughout the United States to defend the growing nation from a variety of threats, both perceived and real. Seventeen of these sites are depicted in a collection painted especially for Dthe U.S. Capitol by Seth Eastman. Born in 1808 in Brunswick, Maine, Eastman found expression for his artistic skills in a military career. After graduating from the U.S. Military Academy at West Point, where offi cers-in-training were taught basic drawing and drafting techniques, Eastman was posted to forts in Wisconsin and Minnesota before returning to West Point as assistant teacher of drawing. Eastman also established himself as an accomplished landscape painter, and between 1836 and 1840, 17 of his oils were exhibited at the National Academy of Design in New York City. His election as an honorary member of the academy in 1838 further enhanced his status as an artist. Transferred to posts in Florida, Minnesota, and Texas in the 1840s, Eastman became interested in the Native Americans of these regions and made numerous sketches of the people and their customs. This experience prepared him for his next five years in Washington, D.C., where he was assigned to the commissioner of Indian Affairs and illus trated Henry Rowe Schoolcraft’s important six-volume Historical and Statistical Information Respecting the History, Condition, and Prospects of the Indian Tribes of the United States. During this time Eastman also assisted Captain Montgomery C. Meigs, superintendent of the Capitol Brevet Brigadier General Seth Eastman. -

Enon Valdez Oil Spill Restoration Project Final Report Site Specific Archaeological Restoration at SEW-440 and SEW-488 Restoration Project 95007B Final Report Linda Finn Yarborough United States Department of Agriculture Forest Service Chugach National Forest 3301 C St., Suite 300 Anchorage, Alaska 99503 October 1997 Site Specific Archaeological Restoration at SEW440 and SEW488 Restoration Project 95007B Final Report Siw:The project effort was initiated under Restoration Project 94007B.An annual progress report was issued in January, 1995 by Yarborough, L., under the title Restoration ~ -1995. Theproject continued under Restoration Project 95007B, the subject of annual this report. A second progress report was prepared in September 1995 by Yarborough, L., under the title 1s Reuort. Seutember 1995. FY 95 wasthe last field season for this project. Data analysis and project report preparation took place in FY 96 and FY97.Papers were prepared for presentation and peer reviewed publication, and results were presented to the public in FY 97. Abstract: Project 94007 provided for restoration of two archaeological sites damaged during the Exxon Vuldez Oil Spill and its subsequent cleanup program. Test excavations were carried out at both SEW-440 and SEW-488 during 1994. Analysis and completion of excavations at SEW-488 took place in 1995. Analysis continued in 1996 and 1997. Each site was assessed in the field and mapped prior to testing. Data recovery work yielded both environmental and cultural information. Both sites appear to have been intermittently occupied, SEW-440 over a period of almost 2000 years, and SEW-488 for up to 3000 years. Artifact and zooarchaeological analyses resulted in information on prehistoric technology, subsistence, seasonality and site use.
