Galápagos-Riesenschildkröten sind ausschließlich auf dem Galápagos-Archipel im Pazifischen Ozean zu finden. Dort leben sie sowohl in regennassen Regionen als auch in Gebieten mit spärlicher Vegetation. Sie sind tagaktiv und wandern vom Hochland zu ihren Eiablageplätzen in wärmeren Küstengebieten. Sie können ein sehr hohes Alter erreichen, in der Regel werden sie 50–80 Jahre alt. Im Jahr 2020 verzeichnete das Europäische Zuchtbuch für Galápagos-Riesenschildkröten 108 Tiere in 23 Zoos und Einrichtungen. In Europa wird diese Art in 12 Zoos gezeigt, darunter in Rostock und Hoyerswerda. Im Jahr 2012 wurden im Rostocker Zoo fünf Tiere gehalten, die alle aus dem Zoo Zürich kamen. Im Juni 2019 wurde eine der fünf Schildkröten, Elvida, tot in ihrem Gehege aufgefunden. Elvida wurde zur Sektion an das Leibniz-Institut für Zoo- und Wildtierforschung in Berlin übergeben. Danach wurde sie im Museum für Naturkunde Berlin präpariert. Die Präparation erfolgte mit einem Imprägnierverfahren, bei dem das Wasser der Zellen durch Polyethylenglykol (PEG) ersetzt wird. Seit Dezember 2020 ist das Exponat der Galápagos-Riesenschildkröte Elvida Teil der Zoologischen Sammlung der Universität Rostock, wo es den Studierenden für Lehrzwecke zur Verfügung steht und Teil der Ausstellung ist. Relocation of a Galapagos giant tortoise from the Zoological Garden to the Zoological Collection Abstract: Galápagos giant tortoises are found exclusively on the Galápagos archipelago in the Pacific Ocean. There they live both in rain-wet regions and in areas with sparse vegetation. They are diurnal and migrate from the highlands to their egg-laying sites in warmer coastal areas. They can reach a very old age, usually they live 50–80 years. In 2020, the European Studbook for Galápagos giant tortoises listed 108 animals in 23 zoos and institutions. In Europe, this species is kept in 12 zoos, including Rostock and Hoyerswerda. Five individuals were kept at Rostock Zoo in 2012, all of which came from Zurich Zoo. In June 2019, one of the five tortoises, Elvida, was found dead in her enclosure. Elvida was handed over to the Leibniz Institute for Zoo and Wildlife Research in Berlin for dissection. After finishing the dissection, it was prepared at the Museum für Naturkunde Berlin. The preparation was carried out with an impregnation procedure in which the water of the cells is replaced by polyethylene glycol (PEG). Since December 2020, the exhibit of the Galápagos giant tortoise Elvida has been part of the Zoological Collection of the University of Rostock, where it is available to students for teaching purposes and is part of the exhibition.

This second Matthew Flinders Memorial Lecture, in a series sponsored jointly by the Royal Institute of Navigation and the Hydrographic Society with the cooperation of Lincolnshire and Humberside Arts was presented at the University of Hull on 11 May 1983 with Sir John Dudding, Chairman of Lincolnshire and Humberside Arts in the Chair. The first lecture, presented by Rear-Admiral G. S. Ritchie in April 1974 (Journal27, 3) on the bicentenary of the birth of Matthew Flinders, described the hydrographic work of this exploring navigator. Miss Ferrar concentrates on the graphical records of Flinders's Australian voyages.When Marco Polo made his journey to China, overland from Venice in the thirteenth century, the lands around the Pacific Ocean were wholly unknown to Europeans. But the silks and spices with which he returned sowed the seeds of the quest for a sea route to the ‘Spice Islands’ which was to be one of the mainsprings of exploration for nearly 500 years. The Spaniards crossed the Atlantic. But instead of finding themselves on the coast of Asia as they had expected they discovered the lands (and the wealth) of the Aztecs and Incas, and their explorations extended along the Pacific coasts of Central and South America from Mexico to Peru. The Portuguese found their way around southern Africa and across the Indian Ocean to South-east Asia, where they attained their objective and established a lucrative trade with the Spice Islands. Sailing ship routes depend upon the direction of prevailing winds, so the outward voyage took them eastwards from the Cape of Good Hope and then northwards to their destination. The homeward crossing of the Indian Ocean was in more northerly latitudes.

Abstract Covering nearly one third of the Earth's surface, the Pacific Ocean contains many significant interconnected geologic features extending into the coastal zone and the islands themselves. Trenches, ridges, seamount chains, faults, and fracture zones are not only fundamental expressions of Earth processes but also fundamental to life. Without awareness of these features and their natural and cultural importance, marine management and global understanding will remain disjointed. The Ocean Exploration Trust (OET) will spend the next several years in the Pacific conducting scientific expeditions to better understand the ocean through seafloor mapping and ocean exploration. Western ocean science is one of many ways to perceive and value the structural features of the Pacific. Communities across Pacific islands—often volcanic peaks emerging from deep below—are interconnected by water and by the underlying seafloor. We acknowledge the knowledge from local communities and recognize the multitude of ways to conceptualize and relate to the Pacific. With the University of Rhode Island's Coastal Resources Center (CRC), OET seeks to collaborate with local communities to reveal the structural significance and interconnected nature of oceanic features, making a link to the livelihoods of Pacific islanders. Further objectives would be co-designed with partners from local communities.

To date, the poecilosclerid sponge genus Pozziella Topsent, 1896 was represented by two species: Pozziella clavisepta Topsent, 1896 and Pozziella aperta (Topsent, 1920), which are presently redescribed. During the campaign SO 144-3a of the project PAGANINI in the Pacific Ocean between the Galapagos Archipelago and Central America, three new species were recovered and are described here: Pozziella cerilla sp. nov., Pozziella neuhausi sp. nov. and Pozziella lueteri sp. nov. The present study led to a revision of the genus and an attempt to resolve the relationships between the species, based on the likeness of spicule complements and biometric characters. A similarity analysis revealed that Atlantic and Pacific species clustered separately. In addition, a key to all species of the genus based on spicular characters is provided.

The University of Hawai‘i at Mānoa is the flagship campus for the country’s most remote and westernmost state. It lies over two thousand nautical miles from the nearest continent, roughly in the center of the Pacific Ocean, the largest division of the world hydrosphere. Until 1893, Hawai’i was a sovereign kingdom. In 1959, the U.S. government annexed Hawaiʻi as the last and newest of its fifty states. This vivid context—Pacific, Asian, Hawaiian, American, postcolonial—constitutes both a geographical and cultural orientation. In view of these numerous, vivid conditions, our paper offers a single case study based on small projects underway at Mānoa, where the senior leadership of the university invited the newly established University of Hawai‘i Community Design Center to address the chronic disrepair of campus buildings and public spaces through low-cost, high-impact design interventions. The aim of these interventions is to improve perceived qualities of public space and campus character, which have suffered under the weight of the university’s half-billion dollar deferred maintenance backlog.

Radiocarbon (Δ14C) measurements of monthly samples from a Galapagos surface coral are among the first data sets from the new Keck Carbon Cycle Accelerator Mass Spectrometry laboratory at the University of California, Irvine. An average Δ14C value of −62 is obtained for 144 measurements of samples from monthly coral bands that lived from about AD 1760–1771 (±6 yr). High Δ14C values were found during January through March, when upwelling was weak or absent at the Galapagos Islands. Low Δ14C values were obtained mid-year during strong upwelling. The average seasonal variability of Δ14C was 15–25, which is greater than that at other tropical and subtropical locations in the Pacific Ocean because of intense seasonal upwelling at this site. Periods of sustained high Δ14C values were found during 1762–1763 and 1766. A spectral analysis revealed that the spectral density for the Δ14C data displays most of its variance at the 5-yr cycle, which is reflective of El Niño periodicity during the 20th century.

AbstractMost, but not all cnidarian species in the classes Hydrozoa, Scyphozoa and Anthozoa have a life cycle in which a colonial, asexually reproducing hydroid phase alternates with a free-swimming, sexually reproducing medusa phase that, in the hydrozoans, is usually microscopic. Hydrozoan medusae were collected by zooplankton tows in Newport Bay and the Pacific Ocean near Newport Beach, California, and hydroid colonies were collected from solid substrates in the same areas. Specimens were documented by videomicroscopy, preserved in ethanol, and sent to the Canadian Centre for DNA Barcoding at the University of Guelph, Ontario, Canada for DNA barcoding.Among the order Anthomedusae (athecate hydroids), DNA barcoding allowed for the discrimination between the medusae of eight putative species of Bougainvillia, and the hydroid stages were documented for two of these. The medusae of three putative species of Amphinema were identified, and the hydroid stages were identified for two of them. DNA barcodes were obtained from medusae of one species of Cladonema, one adult of the By-the wind Sailor, Velella Velella, five putative species of Corymorpha with the matching hydroid phase for one; and Coryne eximia, Turritopsis dohrnii and Turritopsis nutricula with the corresponding hydroid phases. The actinula larvae and hydroid for the pink-hearted hydroid Ectopleura crocea were identified and linked by DNA barcoding.Among the order Leptomedusae (thecate hydroids) medusae were identified for Clytia elsaeoswaldae, Clytia gracilis and Clytia sp. 701 AC and matched with the hydroid phases for the latter two species. Medusae were matched with the hydroid phases for two species of Obelia (including O. dichotoma) and Eucheilota bakeri. Obelia geniculata was collected as a single hydroid. DNA barcodes were obtained for hydroids of Orthopyxis everta and three other species of Orthopyxis.The medusa of one member of the family Solmarisidae, representing the order Narcomedusae, and one member (Liriope tetraphylla) of the order Trachymedusae were recognized as medusae.In the Scyphozoa, DNA barcoding confirmed the planktonic larval stage (ephyra) of the Moon Jelly, Aurelia aurita, the adult medusa of which is occasionally common in and around Newport Bay. In the Anthozoa, antipathula larvae were identified from the Onion Anemone, Paranthus rapiformis and a cerinula larva was identified from the Tube-dwelling Anemone, Isarachnanthus nocturnus. We have yet to find the adults of these species locally.

Previous climatologies of blocking from this group using a one-dimensional index showed that in the Northern Hemisphere, blocking onsets primarily occurred in the Pacific Ocean region, the eastern Atlantic, and over continental Asia. In the Southern Hemisphere, the western and eastern Pacific are the two active regions for block onset. The development of technologies such as Geographic Information System (GIS) visualization software mean that ingesting data and then rendering it on a map has become easier and faster. This research group has previously not archived the latitude of onset, making a comparison of onset locations with 2-D indexes difficult. Now, the onset latitude is provided on the University of Missouri Blocking Archive. This work shows that the blocking onset regions are roughly consistent with those found by 2-D indexes, but there are some key differences based on the differences in the information presented. Here, block onset locations are slightly equatorward and upstream of those presented in 2-D indexes. Additionally, there are some differences in the onset locations for more persistent blocks and stronger blocks versus their less persistent and weaker counterparts.

Recently, an opportunity for a pathfinder mission towards a new neutrino telescope appeared in the Pacific Ocean. An existing deep-sea electrooptical infrastructure maintained by Ocean Networks Canada could pose as the base towards a potential new large-volume neutrino telescope. Two groups from Technical University Munich and the University of Alberta pursued the optical characterization of the 2.6 km deep site calledCascada Basinwithin the scope of the “Strings for Absorption length in Water” (STRAW) project. We present a summary of the 1-year construction timeline, impressions of the detector performance and first results.
