Principal Component Analysis of the Summertime Winds over the Gulf of California: A Gulf Surge Index

A principal component analysis of the summertime near-surface Quick Scatterometer (QuikSCAT) winds is used to identify the leading mode of synoptic-scale variability of the low-level flow along the Gulf of California during the North American monsoon season. A gulf surge mode emerges from this analysis as the leading EOF, with the corresponding principal component time series interpretable as an objective index for gulf surge occurrence. This index is used as a reference time series for regression analysis and compositing meteorological fields of interest, to explore the relationship between gulf surges and precipitation over the core and marginal regions of the monsoon, as well as the manifestation of these transient events in the large-scale circulation. It is found that, although seemingly mesoscale features confined over the Gulf of California, gulf surges are intimately linked to patterns of large-scale variability of the eastern Pacific ITCZ and greatly contribute to the definition of the northward extent of the monsoonal rains

Britain’s decision to withdraw from the Persian Gulf: a pattern not a puzzle

The reasons for the British decision to withdraw from the Gulf are highly contentious. While some scholars have focused on short-term considerations, especially the devaluation of sterling towards the end of 1967, in the British determination to quit the Gulf, others have concentrated on longer-term trends in British policy-making for the region. This article sides with the latter. Britain's Gulf role came under increasing scrutiny following the 1956 Suez crisis as part of an ongoing debate about the costs and benefits of Britain's Gulf presence. In this sense, British withdrawal fitted into a wider pattern of British decolonisation. By the 1960s, the Treasury, in particular, strongly questioned the necessity and cost-effectiveness of the maintenance of empire in the Gulf to safeguard British economic interests there. Recent interpretations which seek to disaggregate the British decision to leave Southeast Asia from the decision to depart from the Gulf are also questionable. By mid-1967, it had already been determined that Britain would leave both regions by the mid-1970s, the only difference being that this decision was formally announced with respect to Southeast Asia, but not with regard to the Gulf. The devaluation of sterling in November 1967, therefore, merely hastened and facilitated decisions which had already been taken. Despite the end of formal empire in the Gulf, Britain did seek, not always successfully, to preserve its interests into the 1970s and beyond

Miscarriage, stillbirth and congenital malformation in the offspring of UK veterans of the first Gulf war.

OBJECTIVES: To assess whether the offspring of UK veterans of the first Gulf war are at increased risk of fetal death or congenital malformation. METHOD: This was a retrospective reproductive cohort study of UK Gulf war veterans and a demographically similar comparison group who were in service at the time but were not deployed to the Gulf. Reproductive history was collected by means of a validated postal questionnaire between 1998 and 2001. RESULTS: In all, 27 959 pregnancies reported by men and 861 pregnancies reported by women were conceived after the first Gulf war and before November 1997. The risk of reported miscarriage was higher among pregnancies fathered by Gulf war veterans than by non-Gulf war veterans (OR = 1.4, 95% CI: 1.3, 1.5). Stillbirth risk was similar in both groups. Male Gulf war veterans reported a higher proportion of offspring with any type of malformation than the comparison cohort (OR = 1.5, 95% CI: 1.3, 1.7). Examination by type of malformation revealed some evidence for increased risk of malformations of the genital system, urinary system (renal and urinary tract), and 'other' defects of the digestive system, musculo-skeletal system, and non-chromosomal (non-syndrome) anomalies. These associations were weakened when analyses were restricted to clinically confirmed conditions. There was little or no evidence of increased risk for other structural malformations, specific syndromes, and chromosomal anomalies. Among female veterans, no effect of Gulf war service was found on the risk of miscarriage. The numbers of stillbirths and malformations reported by women were too small to allow meaningful analyses. CONCLUSION: We found no evidence for a link between paternal deployment to the Gulf war and increased risk of stillbirth, chromosomal malformations, or congenital syndromes. Associations were found between fathers' service in the Gulf war and increased risk of miscarriage and less well-defined malformations, but these findings need to be interpreted with caution as such outcomes are susceptible to recall bias. The finding of a possible relationship with renal anomalies requires further investigation. There was no evidence of an association between risk of miscarriage and mothers' service in the gulf

State of Florida Conservation Plan for Gulf Sturgeon (Acipenser oxyrinchus desotoi)

Gulf sturgeon are anadromous. They spend the cooler months (October or November through March or April) in estuarine or marine habitats, where they feed on benthic organisms such as isopods, amphipods, lancets, molluscs, crabs, grass shrimp, and marine worms (Mason and Clugston, 1993). In the spring, gulf sturgeon return to their natal river, where the sexually mature sturgeon spawn, and the population spends the next 6–8 months there (Odenkirk, 1989; Foster, 1993; Clugston et al., 1995; Fox et al., 2000). The conservation plan detailed in this document will be used to aid recovery of gulf sturgeon populations throughout the state of Florida and could be a model for other gulf states to use. (106pp.

Once and Future Gulf of Mexico Ecosystem: Restoration Recommendations of an Expert Working Group

The Deepwater Horizon (DWH) well blowout released more petroleum hydrocarbons into the marine environment than any previous U.S. oil spill (4.9 million barrels), fouling marine life, damaging deep sea and shoreline habitats and causing closures of economically valuable fisheries in the Gulf of Mexico. A suite of pollutants—liquid and gaseous petroleum compounds plus chemical dispersants—poured into ecosystems that had already been stressed by overfishing, development and global climate change. Beyond the direct effects that were captured in dramatic photographs of oiled birds in the media, it is likely that there are subtle, delayed, indirect and potentially synergistic impacts of these widely dispersed, highly bioavailable and toxic hydrocarbons and chemical dispersants on marine life from pelicans to salt marsh grasses and to deep-sea animals. As tragic as the DWH blowout was, it has stimulated public interest in protecting this economically, socially and environmentally critical region. The 2010 Mabus Report, commissioned by President Barack Obama and written by the secretary of the Navy, provides a blueprint for restoring the Gulf that is bold, visionary and strategic. It is clear that we need not only to repair the damage left behind by the oil but also to go well beyond that to restore the anthropogenically stressed and declining Gulf ecosystems to prosperity-sustaining levels of historic productivity. For this report, we assembled a team of leading scientists with expertise in coastal and marine ecosystems and with experience in their restoration to identify strategies and specific actions that will revitalize and sustain the Gulf coastal economy. Because the DWH spill intervened in ecosystems that are intimately interconnected and already under stress, and will remain stressed from global climate change, we argue that restoration of the Gulf must go beyond the traditional "in-place, in-kind" restoration approach that targets specific damaged habitats or species. A sustainable restoration of the Gulf of Mexico after DWH must: 1. Recognize that ecosystem resilience has been compromised by multiple human interventions predating the DWH spill; 2. Acknowledge that significant future environmental change is inevitable and must be factored into restoration plans and actions for them to be durable; 3. Treat the Gulf as a complex and interconnected network of ecosystems from shoreline to deep sea; and 4. Recognize that human and ecosystem productivity in the Gulf are interdependent, and that human needs from and effects on the Gulf must be integral to restoration planning. With these principles in mind, the authors provide the scientific basis for a sustainable restoration program along three themes: 1. Assess and repair damage from DWH and other stresses on the Gulf; 2. Protect existing habitats and populations; and 3. Integrate sustainable human use with ecological processes in the Gulf of Mexico. Under these themes, 15 historically informed, adaptive, ecosystem-based restoration actions are presented to recover Gulf resources and rebuild the resilience of its ecosystem. The vision that guides our recommendations fundamentally imbeds the restoration actions within the context of the changing environment so as to achieve resilience of resources, human communities and the economy into the indefinite future
