Picture of Argentinian Coast.OILMAP, CMS, WQMAP and COASTMAP is implemented in the "Plataforma Continental Patagónica Argentina"

The Argentinian Federal Government is implementing a series of far reaching protection measures of one of the world's largest continental shelfs; La Plataforma Continental Patagonica Argentina. This vast water body, approximately one million square miles, includes the jurisdictional waters of the Provinces of Chubut, Rio Negro, Santa Cruz and Tierra del Fuego, Antártida e Islas del Atlántico Sur and other waters under Argentinian state control. The anticipated increase in shipping and offshore exploitation activities require that these measures include the protection of both domestic and adjacent international waters, with particular emphasis on reinforcing the government's pollution preventative systems and capabilities.
To assist in this task, the World Bank, an implementing agency of the Global Environment Facility Program (GEF), has provided a grant to the Argentinian federal government to develop suitable operational response tools to help manage the protection of this important marine resource. As part of this process, ASA is implementing a suite of ASA's software, including; OILMAP, CMS, WQMAP, and COASTMAP. ASA South American (ASASA), together with ASA Inc and ASA´s agent in Argentina (Morken AS) is working closely with a team of modeling experts from the Prefectura Naval Argentina (PNA) and Servicio de Hidrografía Naval (SHN) to implement the systems, and a series of software training programs.
OILMAP the oil spill trajectory and fates model, together with an interactive GIS and environmental data tools predict the surface trajectory of spilled oil for either instantaneous or continuous release spills and is used to assess the potential for impacts from accidental releases of oil. The CMS (Crisis Management System) module allows the user to manage personnel, response equipment and other resources during training or an actual incident. WQMAP, an integrated modeling system designed to study surface water quality issues allows the user to develop computational grids, and perform hydrodynamic simulations, and COASTMAP provides environmental data management and analysis.

Water Quality Study Uses Modeling and DNA Fingerprinting Analysis

For years, people have been concerned about pollution in New Bedford Harbor, with a "red flag" raised over what human beings and water treatment plants might be dumping into the bay. A recently completed study of water quality in New Bedford Harbor, commissioned by the New Bedford Harbor Trustee Council and conducted by Applied Science Associates (ASA), took a new approach to evaluate sources contributing pollution to the harbor. The study combined a field sampling program and computer modeling with DNA fingerprinting analysis to identify and quantify sources contributing fecal coliform (FC) to the waters of Outer New Bedford Harbor.Picture of New Bedford Harbor

The study began with a field survey conducted by EA Engineering, Science and Technology, Inc., under the direction of ASA, to characterize the FC sources contributing to and resulting FC levels found in the harbor. Water samples were collected at 21 stations in and around New Bedford Harbor. These stations were carefully selected so as to adequately characterize the origins and magnitudes of the FC sources. Sampling began in April 2002 and continued until July 2003. The field program included intensive sampling of two storm events. Water samples from the field program were then subjected to two different DNA fingerprinting analyses (DNA Ribotyping and the F-Specific [F+ or FRNA] coliphage analysis) to determine the biological origin of the FC at each of the identified sources. Finally, a modeling study was undertaken to evaluate the effect of each of the identified sources on the distribution of FC in the outer harbor. Hydrodynamic modeling of Outer New Bedford Harbor was performed to obtain detailed currents in the harbor using ASA's Boundary Fitted Hydrodynamic (BFHYDRO) model. Results from the hydrodynamic model were then used in conjunction with data on FC source concentrations from the field survey to conduct a series of pollutant fate and transport simulations using ASA's Boundary Fitted Mass Transport (BFMASS) model.

The conclusions from the computer modeling, combined with the DNA fingerprint analysis, indicate that humans are a minor source of FC relative to other animals for New Bedford Harbor. DNA fingerprinting techniques indicate that birds are the dominant source of FC in the harbor, with rodents and raccoons also significant contributors. Humans were found to account for only a small fraction (~7-15%) of the total FC entering the outer harbor. The study was able to distinguish fecal coliform from humans, goose, rats, deer, seagulls, raccoons, horses and cows in the New Bedford area. Overall, FC concentrations were found to be relatively low throughout most of the harbor, with higher concentrations limited to near-shore areas. FC counts during the storm events were significantly higher than those observed during dry periods.

BHP Billiton Commissions Asia-Pacific ASA To Prepare Standardized Oil Spill Response Plan Manual For Their Global Operations

BHP Billiton Ltd is a global company with assets based in the UK, Middle East, Africa, Australia and the Americas. These global activities are managed from four centres and include oil and gas exploration, drilling, construction, production and transport operations. As such, a need was recognised within the organisation to standardise each operations approach to emergency response management.

BHP Billiton commissioned Asia-Pacific ASA (APASA) to prepare an Oil Spill Response Manual to be used by all of their management centres as a guideline to writing and maintaining Oil Spill Contingency Plans. The guidelines manual was not designed to be used in the event of a spill, but to ensure that all of the company's oil spill contingency plans are standardized for each global operation. The manual is broad in scope to cover the geographic diversity of their operations and provides checklists to meet a variety of preparedness and response considerations.

The guidelines manual includes:
" BHP Billiton's organisational structure and management processes.
" Explanation of the roles in an emergency response situation, following the Incident Command System (ICS) structure.
" Step by step checklists for each Oil Spill Response Team role.
" Forms used by emergency response personnel to assist in the flow of information, resource management and incident status.
" Toolkits to assist in decision making.

The ICS structure is a flexible system, which provides for rapid expansion or reduction in the size of the response team according to different response needs. This has been adopted throughout BHP Billiton, ensuring an integrated company-wide response.

ASA Personnel News

Sasha Zigic and Brian King were the keynote speakers at an "Offshore Drilling Workshop" organized by International Environmental Management Co. Ltd in Bangkok, Thailand. The purpose of the workshop was to provide a forum in which personnel from government agencies and the oil industry could raise and address questions about ASA's sediment and solute model, MUDMAP, which has/is used extensively to simulate mud and cuttings discharges into the Gulf of Thailand.

Thailand's Pollution Control Department (PCD) and Chulalongkorn University recently purchased ASA's oil spill model, OILMAP for Arcview, to assist in planning and emergency decision making for the Gulf of Thailand. Ten of the PCD staff underwent an intensive three-day training course carried out by members of the Asia-Pacific office, Sasha Zigic and Brian King. The training course provided a thorough understanding of how the OILMAP for Arcview system in conjunction with PCD's extensive Arcview GIS database can be used for spill exercises, response and as a prosecution tool in the event of a spill. The Gulf of Thailand is a semi-enclosed sea, measuring approximately 400km by 800km, covering an area of about 320,000 square kilometers. Millions of people derive their livelihood from fish and mineral resources produced from the Gulf, and millions more can/are affected by changes in the environment of the Gulf.
