The 2010 Deepwater Horizon (DWH) explosion in the Gulf of Mexico led to the largest ever marine oil spill by volume. The GuLF STUDY is investigating possible adverse human health effects associated with oil spill activities. One objective of the study was to utilize biological specimens from study participants to examine spill-related adverse health effects. This study describes the methods for...

The Deepwater Horizon oil spill impacted Louisiana's coastal estuaries physically, chemically, and biologically. To better understand the ecological consequences of this oil spill on Louisiana estuaries, we compared the abundance and size of two Gulf shrimp species (Farfantepeneus aztecus and Litopeneus setiferus) in heavily affected and relatively unaffected estuaries, before and after the oil...

The paper analyses the effect of R&D and technology import on firm performance in Shanghai. We consider R&D and technology spill-over to be heterogeneous treatments, and using econometric matching, we account for possible selection bias. Our results suggest that, when compared to companies without any treatment, firms that receive either or both of our treatments yield positive effects. Technol...

Interbank claims are a concern to regulators as they might facilitate the dissemination of defaults and generate spill-over effects. Building on a simple model, this paper introduces a measure of the spill-over effects that a bank generates when it defaults. The measure is based on an explicit criterion, the aggregate debt repayments, and is bank’s specific, affected by the bank’s characteristi...

This paper is part of a work program concerning the modeling of object drift in near coastal ocean waters over a several week time period. The final target of this program is to develop methods to forecast the drift of things like containers, lost objects or oil spill over long periods of time in near coastal ocean areas. Such methods would be of interest for services in charge of maritime safe...

With increasing oil exploration in Arctic regions, the risk of an accidental oil spill into the environment is inevitably elevated. As a result, concerns have been raised over the potential impact of oil exposure on Arctic organisms. This study assessed the effects of an acute oil exposure (mimicking an accidental spill) on the immune function and oxidative stress status of the Arctic scallop C...

The tanker Nakhodka oil spill in the Sea of Japan was happened on January 2 1997 and this accident caused serious environmental damages. After the accident, discussions and collaborations involving citizens and government have been started to make significant steps to protect natural environment of river banks, mountains and hills in the vicinity of human residents and these activities seem to ...

because of environmental sensitivity of the caspian sea, any subsea oil spills and blowouts can inflict destructive impacts on marine environment and cause catastrophic damage in the area. employing mathematical simulation is one of the easiest and most effective prediction tools for understanding the oil spill behavior under various environmental forces. in this regard, mike3d simulation packa...

An increase in exploited species within marine reserves is often expected to benefit adjacent fished areas through the movement or ‘spill-over’ of across reserve boundaries. However, harvest at and near boundaries can also decrease abundances inside reserves, forming ‘edge-effects’. Spatial analysis gradients abundance have been used interpret extents edge-effects spill-over. While shape these ...

Spill, used to assist the downstream passage of juvenile Chinook salmon (Oncorhynchus tshawytscha), and steelhead (O. mykiss) at eight dams in the Columbia/Snake River hydrosystem may delay the upstream passage of the adults. To evaluate the potential effects of spill on adult passage we evaluated the historical relationship between the day-to-day variations of spill and upstream fish passage a...
