Introduction: Neurological symptoms after breath-hold (BH) diving are often referred to as "Taravana" and considered a form of decompression sickness. However, the presence of "high" gas embolism after BH diving has never been clearly shown. This study showed high bubble formation after BH diving. Materials and methods: We performed transthoracic echocardiography on a 53-year-old male spearfishing diver (180 cm; 80 kg; BMI 24.7) 15 minutes before diving and at 15-minute intervals for 90 minutes after diving in a 42-meter-deep pool. Number of dives, bottom time and surface intervals were freely determined by the diver. Dive profiles were digitally recorded for depth, time and surface interval, using a freediving computer. Relative surface interval (surface interval/diving time) and gradient factor were calculated. Results: High bubble grades were found in all the recorded echocardiograms. From the first to third recording (45 minutes), Grade 4 Eftedal-Brubakk (EB) bubbles were observed. The 60-, 75- and 90-minute recordings showed a reduction to Grades 3, 2 and 1 EB. Mean calculated GF for every BH dive was 0.22; maximum GF after the last dive was 0.33. Conclusions: High bubble grades can occur in BH diving, as confirmed by echocardiographic investigation. Ordinary methods to predict inert gas super- saturation may not able to predict Taravana cases. ; This document is the accepted Authors' Copy of the paper published in UHM 2016, 43(4): 449-455.

ABSTRACT Scuba diving has attracted increased numbers of tourists on a global scale. While the beneficial as well as detrimental impacts of scuba diving tourism have been well documented, limited research attention is given to the perspectives of dive operators with respect to sustainable development. This study examined the perspectives and experiences of dive operators in relation to sustainable resource use in Mozambique and Italy, two countries that are home to popular coastal destinations and offshore marine parks. Interviews suggested that overall operators have positive attitudes towards sustainable resource use, engaging in actions such as deploying four-stroke engines, recycling equipment and waste, and favouring electric- over fuel-powered vehicles. Yet, they do not promote sustainable resource use at the dive centre, with reasons including limited time, lack of government incentives, and absence of rebate systems. Implications were discussed for sustainable diving operations in the study areas and generally. ; ACKNOWLEDGEMENTS The authors extend their gratitude to the participants in the interviews, which are included in the list reported here: http://www.greenbubbles.eu/?cat=70.

Dive computers have an important potential for citizen science projects where recreational SCUBA divers can upload the depth temperature profile and the geolocation of the dive to a central database which may provide useful information about the subsurface temperature of the oceans. However, their accuracy may not be adequate and needs to be evaluated. The aim of this study is to assess the accuracy and precision of dive computers and provide guidelines in order to enable their contribution to citizen science projects. Twenty-two dive computers were evaluated during real ocean dives for consistency and scatter in the first phase. In the second phase, the dive computers were immersed in sufficient depth to initiate the dive record inside a precisely controlled sea aquarium while using a calibrated device as a reference. Results indicate that the dive computers do not have the accuracy required for monitoring temperature changes in the oceans, however, they can be used to detect thermoclines if the users follow a specific protocol with specific dive computers. This study enabled the authors to define this protocol based on the results of immersion in two different sea aquarium tanks set to two different temperatures in order to simulate the conditions of a thermocline. ; This paper has received funding from the European Union (EU)'s H2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 643712 to the project Green Bubbles RISE for sustainable diving (Green Bubbles).

ABSTRACT Marine biology is an increasingly preferred study major and career among youth. This is particularly the case of countries with extensive coastlines, such as Italy. In order to understand what exactly is fuelling this trend, and whether it culminates in the successful absorption of marine biologists as valued workforce by society, this study investigated the motivations, satisfaction and career goals of marine biology undergraduate students in Italy. Although it was expected that scientific literacy in formal education plays an important role in motivating marine biology students, the results showed that intrinsic motivations and informal education play a more crucial role. The students consider realistic career options, although these imply having to leave the country. The results of this study were used to make recommendations on the importance of marine and ocean literacy in the formal educational system in Italy, and the general improvement of scientific literacy in formal school education. Recommendations were also made on the potential improvements that can be made by higher education institutions, to better equip marine biologists with the skills required by emerging sectors in society. Finally, considerations were made regarding the dimensioning of supply, offer and marketing of employment opportunities for marine biologists in Italy ; This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Biological Education on 17 October 2017, available online: http://www.tandfonline.com/doi/full/10.1080/00219266.2017.1385509 An embargo period of 18 months applies to this Journal.
