Revolutionizing Underwater Exploration of Autonomous Underwater Vehicles (AUVs) and Seabed Image Processing Techniques

The oceans in the Earth's in one of the last border lines on the World, with only a fraction of their depths having been explored. Advancements in technology have led to the development of Autonomous Underwater Vehicles (AUVs) that can operate independently and perform complex tasks underwater. These vehicles have revolutionized underwater exploration, allowing us to study and understand our oceans like never before. In addition to AUVs, image processing techniques have also been developed that can help us to better understand the seabed and its features. In this comprehensive survey, we will explore the latest advancements in AUV technology and seabed image processing techniques. We'll discuss how these advancements are changing the way we explore and understand our oceans, and their potential impact on the future of marine science. Join us on this journey to discover the exciting world of underwater exploration and the technologies that are driving it forward.Comment: 7 page

Documenting the tropical natural world in the account of Antonio Pigafetta

SFRH/BPD/119899/2016 UIDB/04666/2020 UIDP/04666/2020In the account of his journey of circumnavigation, Antonio Pigafetta (1492-c.1531) noted the uniqueness of the places that he had visited. In addition to peoples and landscapes, he described trees, fruits and herbs, as well as insects, birds, fish and mammals. He referred to numerous species, some of which were new to, or little known in the West. In this essay, I will analyse Antonio Pigafetta’s references to the plants and animals observed during his overseas travels. The species recorded around the world suggest that he was both a keen observer and well resourced. His observations allowed him to describe a world which, united by the oceans, revealed a surprising continuity. For the Italian, many of the vegetable and animal species that he observed in the Americas, on the islands of Southeast Asia or on the vast oceans were similar to others spotted previously, in other regions, by European voyagers. From the Indies to the African coast and from the Atlantic to the Pacific, the globe navigated by Pigafetta demonstrated continuity never before attested to. Crossing boundaries established by political agreements and routes defined by commercial interests, the description of this unified and circumnavigable planet contributed, throughout the 16th century, to the emergence of a new way of understanding nature. In this article, I will seek to identify, in some Early Modern botanical treatises, echoes of this new way of looking at the natural world, as proposed by Antonio Pigafetta.publishersversionpublishe

Mapping the Oceans - Helping Students Make Connections

COSEE-Ocean Systems (OS) is moving forward in its development of effective tools and techniques to aid learners in better understanding the context of the oceans in both the earth and solar systems. Acting upon recent national efforts to "map" ocean topics into the educational standards, COSEE-OS is piloting effective ways to bring the relevance of the oceans to classrooms. This resource introduces concept mapping and demonstrates its effectiveness. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school, Undergraduate lower division, Undergraduate upper division, Graduate or professional

Global Impacts Report 2017

Our fifth Global Impacts Report reflects on the progress of the MSC over the past 20 years, examines the sustainability performance of certified fisheries around the world and highlights areas of future interest

Rockhounding, Seafaring, and Other Material Tales for the End of the World

In the face of accelerated environmental degradation and climate instability, the future of the Earth and of all life on earth is difficult to visualize. Therefore, the different mediums through which we consider environmental issues are just as important as the actions we take to address them. Focusing on three projects combining art, science, and activism, this article suggests a compilation of material tales. They tell stories of plastic rocks and aluminum nuggets where the protagonists are partly finely crafted objects, partly waste materials, and sometimes both at once. Artists Kelly Jazvac, Yesenia Thibeault-Picazo, and the collective Studio Swine collaborate with scientists to offer different ways of experiencing environmental issues through objects and their materiality. They do so by cumulating gestures of making and collecting as a strategy to cope with our current epoch and to imagine its unfolding

'My Father’s Daughter': Filial Dislocation in Shirley Geok-lin Lim’s Poetry

Drawing on the father figure and the father–daughter dynamic in Shirley Geok-lin Lim’s poetry, this article examines how the motif of filial dislocation underlines ambivalent and complicated emotions and meanings that can be traced back to the poet’s traumatic childhood experience of her father’s violence. This experience, described here as one of acute psychical and emotional rupture and dislocation, has been imprinted onto Lim’s body and consciousness in the form of embodied memories and emotions, and reenacted in writing and poetic articulation where the father figure is concerned. Through the recurring themes of memory, (dis)connection, distance, and dislocation, Lim’s deeply personal, even autobiographical, poems explore the wounded father–daughter relationship; in so doing, they trouble the ideological premise of filial piety as a cultural concept, which upholds the child’s obligation to the parent through the performance of filial care, respect, and obedience. At the same time, Lim’s poems reflect how embodied memories and emotions are relived and refelt in the process of writing as well as the depth of the poet’s emotional response and subjective interiority in the articulation and performance of filial and gender identity. Weaving through and traversing interior and exterior spaces and landscapes of memory and imagination, body and geography, the poems illuminate complex psychological, emotional, and embodied dimensions of Lim’s mediation of her filial and gender identity as a feminist poet, a daughter, and a gendered individual

On the value of early marine weather observations: The Malaspina expedition (1789–94)

Great advances in meteorological science were made in the late eighteenth century. In particular, meteorological instruments were carried on ships and the first systematic meteorological readings over the oceans were made. One of these collections of instrumental meteorological readings was carried out by the Malaspina expedition (1789–94), organized by the Spanish Crown to study its vast possessions around the world. We have recovered meteorological variables such as air temperature (maximum and minimum), atmospheric pressure (maximum and minimum), wind (intensity and direction), and appearance (state of the sky) from the documentation generated by the explorers during the journey. In total, nearly 13, 000 instrumental data have been digitized and rescued from this maritime expedition. The comparison of daily temperature and pressure observations with reanalysis and weather stations data shows a good overall agreement. Moreover, apparent discrepancies during several anchored periods have allowed for testing the consistency and quality of these early instrumental marine weather readings

Europa, Another Water Moon?
