Contact between humans and the marine environment is increasing, but the capacity of communities to adapt to human presence remains largely unknown. The popularization of SCUBA diving has added a new dimension to human impacts in aquatic systems and, although individual-level impacts have been identified, cumulative effects on ecosystem function and community-wide responses are unclear. In prin...

In 1986 Wilmshurst and colleagues obse recreational scuba diver after a 15 minute dive embolism (VGE) passing through a previou Embolization of thrombus through a patent foram (2), and the concept of venous to arterial emboliz common after recreational dives but usually silen could traverse an intracardiac shunt and cause i brain and spinal cord. While large atrial sep Wilmshurst’s case are rar...

We assessed four potential sources of error in estimating size of the population of Devils Hole pupfish (Cyprinodon diabolis): net, time of day, diver, and order of diver. Experimental dives (3/day) were conducted during 4 days in July 2009. Effects of the four sources of error on estimates from dive surveys were analyzed using a split-split plot ANOVA. Diver and order of diver had no significa...

DESCRIPTION A 32-year-old scuba diver was admitted to the emergency department for distinct cutaneous lesions. Following an uneventful dive, his peers suspected of several lesions over his body pertaining to decompression sickness (DCS). After his initial assessment, he was referred to the underwater and hyperbaric medicine department for consultation. The patient was a senior diver and denied ...

A portion of Hillsborough Bay (Tampa, Florida, USA), part of the Tampa Bay estuary, undergoes annual summer defaunation, presumably due to hypoxia. Dissolved oxygen levels are very low (< 1.0 mg 1-l) at the times of the defaunations. In the ensuing period between defaunations, recolonization occurs. Monthly samples for 42 consecutive months were collected by SCUBA-diver-operated, hand-held PVC ...

So far, perch egg strands have been considered unpalatable biological material. However, we repeatedly found egg strands of European perch (Perca fluviatilis) in the diet of European catfish (Silurus glanis) caught by longlines in Milada and Most Lakes, Czech Republic. The finding proves that perch egg strands compose a standard food source for this large freshwater predatory fish. It extends t...

Monitoring temperature of aquatic waters is of great importance, with modelled, satellite and in-situ data providing invaluable insights into long-term environmental change. However, there is often a lack of depth-resolved temperature measurements. Recreational dive computers routinely record temperature and depth, so could provide an alternate and highly novel source of oceanographic informati...

Background: A number of occupations and professions may be associated with unique hazards relevant to urologic care. Case Presentation: We relate the presentation, care, and the occupational hazard of urinary tract infection (UTI), presenting as cystitis and pyelonephritis, with stone formation in a scuba diver. The patient voiced concern that his diving suit malfunction was related to his UTI ...
