Summary: Exposure to crude oil can cause various pathological effects in birds, but not all species develop Heinz bodies or anemia. In a study on zebra finches, high doses of oil led to increased reticulocyte percentage and mean corpuscular hemoglobin concentration, as well as inflammation and lymphocyte proliferation, but no Heinz bodies were found. Further research is needed to understand factors contributing to anemia resulting from oil exposure in birds.

Summary: The 2010 Deepwater Horizon oil spill had an impact on the spawning season of coastal species like red drum, which develop rapidly and are sensitive to crude oil exposure. Despite increased pericardial area in red drum larvae exposed to oil, cholesterol biosynthetic genes were not affected. However, free cholesterol levels in the larvae increased significantly, potentially playing a role in the observed oil toxicity across fish species.

Summary: The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 was the largest in US history, causing extensive damage to coastlines and significant economic losses. This review article discusses the journey of the oil from the wellhead to the spill, focusing on its behavior on the water surface and the impact of ocean currents and waves. It also explores the formation of oil-particle aggregates.

Summary: The study examined the impact of polycyclic aromatic hydrocarbons (PAHs) on the vertebrate stress axis and found that marine vertebrates exposed to Deepwater Horizon (DWH) PAHs may experience stress axis impairment. Chronic stress combined with PAH exposure further exacerbated these effects. The mechanism of impairment may involve downregulation of cyclic adenosine monophosphate (cAMP) and 5-hydroxytryptamine (5-HT) acting as a secondary cortisol secretagogue.

Summary: According to oil fate modeling of the Deepwater Horizon spill, the majority of the oil either surfaced or entered the deep plume sediment. A small percentage was removed by responders, and a portion remained in the water column. Non-volatile and soluble fractions degraded by the end of August, leaving residual oil to potentially settle. The model estimates were validated through field observations of floating oil and atmospheric emissions.

Summary: This study examines the effectiveness of subsea dispersant injection (SSDI) during the Deepwater Horizon oil spill and evaluates the potential alternatives if dispersants were not used or used more aggressively. The results show that the actual use of SSDI reduced risk to varying degrees, but more effective use of dispersants could have significantly reduced exposures and relative risks across the ecosystem.

Summary: The Gulf of Mexico Research Initiative (GOMRI) has conducted in-depth studies on the 2010 Deepwater Horizon oil spill from various perspectives and recently assessed the program's accomplishments. By compiling 330 published applications and focusing on modeling efforts, GOMRI has made significant advancements in integrating diverse disciplines and domains. Various modeling tools have been utilized, with a focus on circulation models coupled with other environmental factors to track the fate of oil and its impact on ecosystems and human health.

Summary: Tracking the subsea oil plume during the Deepwater Horizon Oil Spill was conducted using both in situ fluorescence and discrete sample chemical analyses. Discrete samples provided a coarse picture of the oil plume footprint, while in situ fluorescence data improved the resolution. Through analysis of millions of continuous data points, fluorescence was found to serve as a proxy for BTEX concentration.

Summary: Crude oil exposure may lead to developmental defects and transcriptional changes in the kidney of fish. Experimental exposure of red drum larvae showed reduced survival in hypoosmotic waters and altered transcription of kidney-related genes.

Summary: The exposure to high-energy water accommodated fractions (HEWAF) of oil during early life stages impaired pronephros development in zebrafish, leading to reduced or inhibited pronephros fluid clearance capacity and increased edema formation, as indicated by both transcriptional and morphological analyses.

Summary: The Deepwater Horizon oil spill was the largest and deepest oil accident in US waters, with significant impacts on the marine ecosystem. The released oil underwent various mechanisms, including biodegradation, to transform and disperse, with some sedimenting onto the seafloor. Further research efforts have greatly increased our understanding of the fate of spilled oil, focusing on factors such as photooxidation, microbial communities, and marine oil snow formation.
