Florida Bay: Water quality status and trends, historic and emerging algal bloom problems

Florida Bay is a unique subtropical estuary that while historically oligotrophic, has been subjected to both natural and anthropogenic stressors, including hurricanes, coastal eutrophication and other impacts. These stressors have resulted in degradation of water quality in the past several decades, most evidenced by reoccurring blooms of the picocyanobacterium Synechococcus spp. Major nutrient inputs consist of freshwater flows to the eastern region from runoff and regulated canal releases, inputs from the Everglades to the central region via Taylor Slough, exchanges with the Gulf of Mexico, which include intermittent Shark River inputs to the western region, stormwater and wastewater from the Florida Keys, and atmospheric deposition. These nutrient inputs have resulted in a transition from strong phosphorus (P) limitation of phytoplankton in the eastern bay to nitrogen (N) limitation in the western bay. Large blooms of Synechococcus were most pronounced in the central bay region, in the area of transition between P and N limitation, in the mid-1990s. Although non-toxic, these blooms, which have continued intermittently through the early 2000s, resulted in significant sea-grass and benthic organism mortalities. A new suite of stressors in 2005, including the passages of Hurricanes Katrina, Rita, and Wilma, additional canal releases, and the initiation of road construction to widen the main roadway leading to the Keys, were correlated with a large Synechococcus bloom in the previously clear, strongly P- limited, northeastern region of the bay. Sustained for 3 years, this bloom was accompanied by a shift from P limitation to N limitation during its course. Nutrient bioassay experiments suggest that this bloom persisted due to the ability of Synechococcus to access organic N and P sources, microbial and geochemical cycling of organic and inorganic nutrients in the water column and between the water column and sediments (both suspended particles and benthos), and decreased grazing by benthic fauna due to their die-off.

Morphology and Typification of Mastogloia Smithii and M. Lacustris, with Descriptions of Two New Species from the Florida Everglades and the Caribbean Region

The names Mastogloia smithii Thwaites ex Smith and M. smithii var. lacustris Grunow have been attributed to a variety of related diatom morphologies, partly due to the poor availability of type material and complicated nomenclatural history. The history is detailed, clarifying the type morphologies of M. smithii and reconfirming a neglected elevation of M. smithii var. lacustris to M. lacustris (Grunow) Grunow. Populations reported as M. smithii and M. lacustris from the temperate zone (Ontario, Canada and Iowa and Michigan, USA), karstic wetlands of the subtropical Everglades (Florida, USA) and the tropics (Jamaica, Mexico and Belize) are compared with each other. Based on morphological differences including density of partecta, striae and areolae, M. calcarea sp. nov. and M. pseudosmithii sp. nov. are described from the Everglades and the Caribbean region, and a lectotype of M. smithii and a neotype of M. lacustris are designated.

Aged embankment imaging and assessment using surface waves

Rapid, non-intrusive surface wave surveys provide depth profiles from which ground models can be generated for use in earthwork condition assessment. Stiffness throughout earthworks controls the behaviour under static and dynamic loads, and characterising heterogeneity is of interest in relation to the stability of engineered backfill and life-cycle deterioration in aged utility and transportation infrastructure. Continuous surface wave methods were used to identify interfaces between fine- and coarse-grained fill in an end-tipped embankment along the Great Central Railway in Nottinghamshire, UK. Multichannel analysis of surface wave (MASW) methods were used to characterise subsurface voiding in a canal embankment along the Knottingley and Goole canal near Eggborough, Yorkshire. MASW methods are currently being used to study extreme weather impacts on the stability of a highplasticity clay embankment along the Gloucestershire–Warwickshire railway near Laverton. Optimal results were obtained using equipment capable of generating and detecting over wide frequency ranges.

Development of accident prediction models for rural highway intersections

A study was done to develop macrolevel crash prediction models that can be used to understand and identify effective countermeasures for improving signalized highway intersections and multilane stop-controlled highway intersections in rural areas. Poisson and negative binomial regression models were fit to intersection crash data from Georgia, California, and Michigan. To assess the suitability of the models, several goodness-of-fit measures were computed. The statistical models were then used to shed light on the relationships between crash occurrence and traffic and geometric features of the rural signalized intersections. The results revealed that traffic flow variables significantly affected the overall safety performance of the intersections regardless of intersection type and that the geometric features of intersections varied across intersection type and also influenced crash type.

Review : "Ghosts...of the Civil Dead" -- John Hillcoat

Synopsis and review of the Australian prison film Ghosts...of the Civil Dead (John Hillcoat, 1988). Drawing heavily from the book In the Belly of the Beast by American author and long-term prisoner Jack Henry Abbott, as well as from the historical and philosophical work of Michel Foucault (the credits include ‘Foucault Authority – Simon During’), Ghosts… Of the Civil Dead is a searing critique of the so-called ‘new generation’ prison system developed in the United States and recently introduced in Australia. Director John Hillcoat and producer Evan English conducted extensive research for the film, including spending time at the National Institute of Corrections, a think tank in Colorado, and visiting numerous institutions like the ‘new Alcatraz’ at Marion Illinois and other maximum security prisons across the United States. Using a mix of professionals and non-actors, including former prisoners and prison guards, the ‘story’ was workshopped during a lengthy rehearsal period with many actual events and experiences of participants incorporated into the film. The end result deliberately blurs the line between American and Australian prison experience to make the political point that what had happened in the US – from where many events and characters, and much of the architecture and design of the prison are drawn – was beginning to happen in Australia. The film emphasises the vicious cycle of institutionalisation, and highlights the role state authorities play in manufacturing, provoking and manipulating violence and fear both in prisons and in wider society as a means to augment policing and surveillance of the population, to oppress the working classes, and to maintain the political status quo...

Modern surgical treatment of otosclerosis

The modern unilateral surgical treatment of otosclerosis started in 1956. Simultaneous bilateral surgery has not been reported in stapes surgery and in case of bilateral otosclerosis ears are operated in two different sessions. Simultaneous surgery would give the patient the opportunity to gain advantages of bilateral hearing within one session, with less time spent in hospital and on sick leave. The mechanism for vestibular symptoms and the exact end organ affected after surgery is still unveiled. This thesis presents the results of experimental simultaneous bilateral stapes surgery, and vestibular symptoms and findings before and after unilateral stapes surgery. In addition, we explore reasons for outpatient failures in otosclerosis surgery. -- Study I examines the outcome of simultaneous bilateral surgery. Hearing was evaluated with standard pure tone and speech audiograms and vestibular apparatus with visual feedback posturography (VFP) during the one-year follow-up. Subjective symptoms and quality of life were assessed with questionnaires. In study II, reasons for outpatient failures in stapes surgery were explored. Forty-seven consecutive stapedotomies and stapedectomies performed by the same surgeon were included, and the effect of failures on hearing results were analysed. Vestibular symptoms and the end organ(s) affected after stapes surgery were investigated in studies III and IV. With video-oculography (VOG), nystagmus was measured preoperatively, and at one week, one month and 3 months postoperatively in the first phase (III). In the second phase (IV), recordings were obtained some hours postoperatively. The hearing results of the simultaneous bilateral surgery were comparable with unilateral surgeries reported. Recovery from the surgery was fast. Significant improvement in performance and quality of life was noted already month after operation in subjective evaluations. Based on these results, simultaneous bilateral surgery is a suitable approach in bilateral otosclerosis Significantly more outpatient failures occurred for medical reasons in the stapedectomy group (13%) than in the stapedotomy group (2%). Stapedotomy should be favoured if outpatient surgery is planned. However, unplanned admission did not worsen the prognosis. VOG measurements in study III did not show any specific type of nystagmus in patients having vestibular symptoms postoperatively. However, VOG measurements immediately after surgery (IV) revealed nystagmus consistent with a minor disturbance of the semicircular canals in 33% of the patients. Subjectively, half of the patients reported vestibular symptoms that were probably of diverse origin, and could have originated from both otolith and semicircular canal parts of the vestibular organ. Since vestibular symptoms and signs are mild, patients may be safely discharged some hours after stapes surgery.

What is coastal climate?

Historical definitions of what determines whether one lives in a coastal area or not have varied over time. According to Culliton (1998), a “coastal county” is defined as a county with at least 15% of its total land area located within a nation’s coastal watershed. This emphasizes the land areas within which water flows into the ocean or Great Lakes, but may be better suited for ecosystems or water quality research (Crowell et al. 2007). Some Federal Emergency Management Agency (FEMA) documents suggest that “coastal” includes shoreline-adjacent coastal counties, and perhaps even counties impacted by flooding from coastal storms. An accurate definition of “coastal” is critical in this regard since FEMA uses such definitions to revise and modernize their Flood Insurance Rate Maps (Crowell et al. 2007). A recent map published by the National Oceanic and Atmospheric Administration’s (NOAA) Coastal Services Center for the Coastal Change Analysis Program shows that the “coastal” boundary covers the entire state of New York and Michigan, while nearly all of South Carolina is considered “coastal.” The definition of “coastal” one chooses can have major implications, including a simple count of coastal population and the influence of local or state coastal policies. There is, however, one aspect of defining what is “coastal” that has often been overlooked; using atmospheric long-term climate variables to define the inland extent of the coastal zone. This definition, which incorporates temperature, precipitation, wind speed, and relative humidity, is furthermore scalable and globally applicable - even in the face of shifting shorelines. A robust definition using common climate variables should condense the large broad definition often associated with “coastal” such that completely landlocked locations would no longer be considered “coastal.” Moreover, the resulting definition, “coastal climate” or “climatology of the coast”, will help coastal resource managers make better-informed decisions on a wide range of climatologically-influenced issues. The following sections outline the methodology employed to derive some new maps of coastal boundaries in the United States. (PDF contains 3 pages)

Fecundity estimates for Maryland Striped Bass

Contemporary striped bass population modeling efforts on coastal stocks point to a reduced population fecundity in Chesapeake Bay being partially responsible for declining reproduction (Anonymous 1985; Boreman and Goodyear 1984). Fecundity values used in these models were based on earlier work by jackson and tiller (1952), lewis and Bonner (1966), Hollis (1967) and Holland and Yelverton (1973). An important feature to the Boreman and Goodyear (1985) model (FSIM) is an accurate determination of the fecundity weight regression equation used to determine the rate of egg deposition over time. Egg deposition models in turn can be used to determine how reproductive potential is changing over time in response to various management actions, i.e. reducing fishing mortality rates. thus it is imperative to follow population stock structure in the Bay system and to develop a contemporary fecundity relationship for striped bass. This report deals with the gonadal material collected in 1986 and 1987 from a coordinated Maryland field program. Samples were obtained from drift gill net collections during the spawning season from four localities: Potomac Estuary, Upper Bay, Chesapeake and Delaware Canal, and the Choptank Estuary (Figure 1).

South Lancashire Fisheries Advisory Committee 15th October, 1975.

This is the report from the South Lancashire Fisheries Advisory Committee meeting, which was held on the 15th October 1975. The report contains sections on planning study for the post 1981 period, reports on fisheries activities, land drainage representation on local committees, proposed new byelaws and fishing licence duties. The section on fisheries activities are reported by area fisheries officers and looks at poaching, Langcliffe and Middleton hatcheries management, number/causes of fish mortalities and biological work carried on Colne Water and Lancaster Canal. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.
