Benthic processes in South San Francisco Bay: The role of organic inputs and bioturbation
No full textMeasurements of benthic processes over the last 13 years in South San Francisco Bay have spanned a range of hydrologic and water quality conditions. However, benthic fluxes of O₂, NH₄⁺ and NO₃⁻ have shown little variation. NH₄ and NO₃⁻ flux during this period were relatively constant in magnitude and direction. Sediment O₂ consumption was lower in the early 1980s than in the early 1990s. The reason for this difference is unclear, but may be a result of methodology or a lower density of the tube dwelling Asychis elongata. Although dissolved inorganic phosphate fluxes generally have been close to zero, in fall, there is a net flux into the sediments. Dissolved Si fluxes were consistently out of the sediments, while dissolved organic carbon fluxes were large and exhibited shifts in direction. Compared with
other estuarine and coastal systems, temperature was not a major control on benthic fluxes because of the small annual temperature range. Irrigation by macrofauna enhances O₂ consumption and may control NH₄⁺ fluxes in the shoals, where NH₄⁺ flux was correlated with the biomass of mollusks. Porewater profiles of NH₄⁺, TCO₂ and radon suggest that irrigation is important in controlling dissolved constituent concentrations. Organic inputs such as deposition of phytoplankton may also affect benthic fluxes. In the channel, NH₄⁺ flux was positively correlated to phaeopigment concentrations in sediments. Ratios of sediment O₂ consumption to DIN (NH₄⁺ + NO₃⁻ ) or DIP flux were very different than ratios of remineralization of organic matter with a Redfield ratio, and suggest that both denitrification and phosphorus burial were occurring at both locations.Conference PaperPublishedAt head of title: Seventy-fifth Annual Meeting of the Pacific Division/American Association for the Advancement of Science held at San Francisco State University, San Francisco, California, June 19-24, 1994

Occurrence, distribution and abundance of cetaceans in Onslow Bay, North Carolina, USA
No full textIn this paper the occurrence, distribution and abundance of cetaceans in offshore waters of Onslow Bay, North Carolina, USA is described. Between June 2007 and June 2010 monthly aerial and shipboard line-transect surveys were conducted along ten 74km transects placed perpendicular to the shelf break. In total 42,676km of aerial trackline (218 sightings) and 5,209km of vessel trackline (100 sightings) were observed. Seven species of cetaceans were observed, but the fauna was dominated strongly by common bottlenose and Atlantic spotted dolphins. Both species were present year-round in the study area. Using photo-identification techniques, five bottlenose dolphins and one spotted dolphin were resighted during the three-year period. In general, the abundance of cetaceans in Onslow Bay was low and too few sightings were made to estimate monthly abundances for species other than bottlenose and spotted dolphins. Maximum monthly abundances of bottlenose and spotted dolphins were 4,100 (95% CI: 1,300–9,400) in May 2010 and 6,000 (95% CI: 2,500–17,400) in March 2009, respectively. Bottlenose dolphins were found throughout the study area, although they were encountered most frequently just off the shelf break. In contrast, spotted dolphins exhibited a strong preference for waters over the continental shelf and were not encountered beyond the shelf break.Peer reviewe

Tokyo Bay Tunnel
No full textDe snelle groei van de Japanse economie sinds 1950 heeft geleid tot een grote vraag naar nieuwe vervoersfaciliteiten en naar verbetering van de oude. Een enorme en explosieve uitbreiding van het bestaande Japanse wegennet is hiervan het gevolg. De Tokyo Bay Ring Road vormt hiervan een klein onderdeel. Het is echter een bijzonder interessant project, vanwege de grote moeilijkheden die de bouwers verwachten te zullen ondervinden in het overbevolkte en aardbevingsgevoelige Kanto district, het zuidoostelijk deel van Honsju. De Tokyo Bay Shore Road is een hoofdweg die zich over 160 km uitstrekt van de monding van de baai bij Yokosuko tot aan de andere kant van de baai bij Futlsu. Samen met de Tokyo Bay Crossing Road en de Bay Mouth Crossing Road vormen deze wegen de Tokyo Bay Ring Road. De reeds door de Japanse overheid geplande Tokyo Bay Crossing Road, die door ons bestudeerd gaat worden, moet de verbinding gaan vormen tussen Kisarazu aan de oost-zijde en Kawasaki aan de west-zijde van de baai. De Bay Mouth Crossing Road zorgt voor de verbinding tussen Yokosuka en Futlsu. In dit afstudeerwerk is een hoofdontwerp gemaakt voor de Tokyo Bay Tunnel.Hydraulic EngineeringCivil Engineering and Geoscience
Sediment pathways in San Francisco South Bay
No full textThis study aims for a better understanding of the sediment pathways in San Francisco South Bay (South Bay). Many issues relevant to the Bay Area community such as shipping, recreational and commercial fishing, habitat restoration, human health, and environmental water quality are reliant on understanding sediment pathways (McKee et al. [2006]). Existing theories suggest that the Sacramento-San Joaquin Delta deliver sediment to South Bay during periods of high river flows. Different hydrodynamic forces, such as the tide, wind and baroclinic flows, redistribute these sediments around South Bay. In this research, trends are analysed using a new set of data (WY2015-WY2017) and sediment pathways in time and space are investigated using a 3D numerical model. In this model, the pathways of three sediment classes with different settling velocities are traced from their source throughout the Bay Area. No such study has yet been undertaken in the South Bay Area. There is a high Delta sediment input to South Bay during periods of high river flow. The local tributaries contribute only marginally to the suspended sediment concentration of South Bay. With a decreasing sediment load from the Delta, the importance of the local tributaries as a sediment source for South Bay could increase. In this research, three different types of sediment exchange between Central Bay and South Bay are observed. The first type is observed during periods of low river flows (Q < 800m3/s). A seaward directed residual flow is found in the channel at Bay Bridge. Sediments are slowly transported out of South Bay. The second type is observed after a period of moderate river flow (Q > 800m3/s). A pulsed sediment flux from the Delta increases the turbidity of Central Bay, resulting in a horizontal spatial variation in SSC from Central Bay to South Bay. The diffusive character of the tide transports the sediments slowly from the turbid Central Bay to the relatively clearer South Bay. The third sediment exchange type is observed after an extreme Delta river flow (QDel ta È 5000m3/s)). The extreme Delta flow refreshes a large part of Central Bay and South Bay. The salinity of Central Bay increases slowly, resulting in a substantially more saline Central Bay than South Bay for a couple of months. The resulting baroclinic flow transports the sediments from Central Bay into South Bay through the landward directed bottom current. Two dominant pathways with opposite transport direction characterise the sediment transport in South Bay. One pathway is located in the channel and is directed southward during periods of high river runoff. The second pathway is located on the extensive east flat and is directed northward during periods of high river runoff. The transport in the channel is dominant during the wet period, resulting in a net transport landward. Besides these two dominant pathways, four re-circulations cells are found, facilitating the exchange between the channel and the shoals. The next step in gaining more insight into the sediment physics is a model studywhich includes bed-interaction with the suspended sediments. A study like this could confirmthe hypotheses opted in this research.Coastal and Marine Engineering and Management (CoMEM
Preparing for Growth and Sustainable Development: Local Government Urban Planning Activities in the Galveston Bay Watershed
No full textpgs. 176-184With land development activity in the Galveston Bay watershed continuing on an unprecedented pace since the early 1990s, various local governments in the bay area are undertaking urban planning and land use management activities for the first time - or much more purposefully than in the past - to deal with the challenges of population growth and ongoing urbanization. As a regional planner for the Houston-Galveston Area Council (H-GAC) during the 1990s, the author also observed the increasing sophistication of many area cities and counties as their increasing population brought them greater resources and program capabilities, as a wider array of people became active in local government as elected officials, and as residents across the region became more environmentally aware and held higher expectations for neighborhood quality and resource protection, as confirmed by public opinion tracking throughout the decade.; The theme of this discussion was that basic urban planning and growth management activities are perhaps the most direct and lasting contributions that local governments in the bay area can make to the long-term conservation and enhancement of the Galveston Bay Estuary and its watershed. Certainly a key component of bay management is how the area's wastewater treatment systems are operated and maintained to limit point source pollution, with many of these facilities under the direct jurisdiction of area cities across the bay watershed. Local governments also have an important role to play in other management areas, such as promoting water conservation, enforcing illegal dumping laws, regulating septic tanks and other on-site wastewater systems, and reducing the environmental impacts of their own government construction projects and maintenance activities
