Received: 19 October 2018; Accepted: 25 December 2018; Published: 29 December 2018 Abstract: Three typhoon events were selected to examine the impact of energy transformation on near-inertial oscillations (NIOs) using observations from a subsurface mooring, which was deployed at 125◦ E and 18◦ N on 26 September 2014 and recovered on 11 January 2016. Almost 16 months of continuous observations were undertaken, and three energetic NIO events were recorded, all generated by passing typhoons. The peak frequencies of these NIOs, 0.91 times of the local inertial frequency f, were all lower than the local inertial frequency f. The estimated vertical −1 group velocities (Cgz) of the three NIO events were 11.9, 7.4, and 23.0 m d , and were relatively small compared with observations from other oceans (i.e., 100 m d−1). The directions of the horizontal near-inertial currents changed four or five times between the depths of 40 and 800 m in all three NIO events, implying that typhoons in the northwest Pacific usually generate high-mode NIOs. -
Micronesica 37(1) Final
Micronesica 37(1):163-166, 2004 A Record of Perochirus cf. scutellatus (Squamata: Gekkonidae) from Ulithi Atoll, Caroline Islands GARY J. WILES1 Division of Aquatic and Wildlife Resources, 192 Dairy Road, Mangilao, Guam 96913, USA Abstract—This paper documents the occurrence of the gecko Perochirus cf. scutellatus at Ulithi Atoll in the Caroline Islands, where it is possibly restricted to a single islet. This represents just the third known location for the species and extends its range by 975 km. Information gathered to date suggests the species was once more widespread and is perhaps sensitive to human-induced habitat change. The genus Perochirus is comprised of three extant species of gecko native to Micronesia and Vanuatu and an extinct form from Tonga (Brown 1976, Pregill 1993, Crombie & Pregill 1999). The giant Micronesian gecko (P. scutellatus) is the largest member of the genus and was until recently considered endemic to Kapingamarangi Atoll in southern Micronesia, where it is common on many islets (Buden 1998a, 1998b). Crombie & Pregill (1999) reported two specimens resem- bling this species from Fana in the Southwest Islands of Palau; these are consid- ered to be P. cf. scutellatus pending further comparison with material from Kapingamarangi (R. Crombie, pers. comm.). Herein, I document the occurrence of P. cf. scutellatus from an additional site in Micronesia. During a week-long fruit bat survey at Ulithi Atoll in Yap State, Caroline Islands in March 1986 (Wiles et al. 1991), 14 of the atoll’s larger islets com- prising 77% of the total land area were visited. Fieldwork was conducted pri- marily from dawn to dusk, with four observers spending much of their time walking transects through the forested interior of each islet. -

The Weeping Monument: a Pre and Post Depositional Site
THE WEEPING MONUMENT: A PRE AND POST DEPOSITIONAL SITE FORMATION STUDY OF THE USS ARIZONA by Valerie Rissel April, 2012 Director of Thesis: Dr. Brad Rodgers Major Department: Program in Maritime History and Archaeology Since its loss on December 7, 1941, the USS Arizona has been slowly leaking over 9 liters of oil per day. This issue has brought about conversations regarding the stability of the wreck, and the possibility of defueling the 500,000 to 600,000 gallons that are likely residing within the wreck. Because of the importance of the wreck site, a decision either way is one which should be carefully researched before any significant changes occur. This research would have to include not only the ship and its deterioration, but also the oil’s effects on the environment. This thesis combines the historical and current data regarding the USS Arizona with case studies of similar situations so a clearer picture of the future of the ship can be obtained.

Numerical Simulations of Typhoon Haishen by a Coupled
Numerical simulations of Typhoon Haishen by a coupled atmosphere-wave ocean model with two different oceanic initial conditions Akiyoshi Wada and Wataru Yanase 1Meteorological Research Institute, Tsukuba, Ibaraki, 305-0052, JAPAN [email protected] 1. Introduction A tropical depression was upgraded to a tropical storm around 22.6˚N, 145.9˚E at 12 UTC on 31 August in 2020, which was named Haishen. Haishen moved southwestward in the early intensification phase and then changed the direction to northwestward from 2 September. During the northwestward movement in the intensification phase, Haishen reached the minimum central pressure of 910 hPa at 12 UTC on 4 September. On 5 September, Haishen changed the direction to north northwestward and entered the East China Sea on 6 September. The Japan Meteorological Agency (JMA) forecasted that Haishen would be extremely strong (below 930 hPa) in the East China and possibly make landfalling in Japan while sustaining the strong intensity. However, Haishen weakened rapidly before entering the East China Sea. In the East China Sea, sea surface cooling was caused by the passage of preceding typhoon, Maysak. However, the cold wake was not sufficiently analyzed in the oceanic initial condition used in the forecast. To investigate the effect of the sea surface temperature (SST) distribution at the initial time and ocean coupling processes on the rapid weakening of Haishen, numerical simulations were conducted by using a nonhydrostatic atmosphere model (NHM) and the coupled atmosphere-wave-ocean model (CPL) (Wada et al., 2018). 2.

As of 1 April (10 a.m., Manila time), Category 4 Typhoon Maysak was located 1,280 km east of Guiuan, Eastern Samar province in central Philippines, with maximum sustained winds of 215 km/h and gusts of up to 250 km/h according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the country's weather bureau. Typhoon Maysak is moving westnorthwest at 17 km/h and is expected to enter the Philippine Area of Responsibility either tonight or in the early morning of 2 April and make landfall along the eastern coast of central Luzon on 4 or 5 April. According to forecast models, Typhoon Maysak is moving towards the Philippines with a diameter of about 700 km and a 24hour rain accumulation of about 100 to 300 mm (considered heavy to extreme). While the typhoon is projected to slightly weaken in the next 24 hours, it may maintain Category 3 status when it makes landfall. On 30 March, the National Disaster Risk Reduction and Management Council (NDRRMC) conducted a PreDisaster Risk Assessment (PDRA) as a preparedness measure. The NDRRMC's PDRA core group reconvened this morning to evaluate the situation. The Emergency Response Preparedness Working Group of the Humanitarian Country Team (HCT) met on 31 March to discuss possible scenarios concerning the typhoon’s expected paths and potential impacts. -

Reptiles of Ngulu Atoll, Yap State, Federated States of Micronesia1
CORE Metadata, citation and similar papers at core.ac.uk Provided by ScholarSpace at University of Hawai'i at Manoa Reptiles of Ngulu Atoll, Yap State, Federated States of Micronesia1 Donald W. Buden2 Abstract: Fourteen species of reptiles (two sea turtles, six geckos, six skinks) are recorded from Ngulu Atoll, Yap, Micronesia, all but the turtles for the first time. None is endemic and most occur widely in Oceania; the phylogenetic status of an undescribed species of Lepidodactylus is undetermined, and a phenotypically male Nactus cf. pelagicus is recorded from Micronesia for the first time. Lepido- dactylus moestus is the most common gecko on Ngulu Island, and Emoia caeruleo- cauda, E. impar, and E. jakati are the most abundant skinks. The islands are an important nesting site for green turtles, Chelonia mydas. Isolation, a small resi- dent human population, and traditional conservation practices contribute to sustaining turtle populations, although occasional poaching by outside visitors persists. The report of a small snake on Ylangchel Island, possibly a species of Ramphotyphlops, requires confirmation. Many of the west-central Pacific islands distribution and relative abundance of the composing Micronesia are poorly known bio- reptiles of Ngulu, and it is based largely on logically, especially the numerous, small, low- my personal observations and specimens that lying, and faunistically impoverished coralline I collected during approximately a month- atolls.

USS Bucyrus Victory (AK-234)
CREWS LETTER (Note: The following informal letter summary of the activities of this ship may be included, in whole or in part, in your letters home. It is not an official Navy release but it is a factual account verified by your commanding officer and it may be published in hometown newspapers or in plant, office, or school papers. Dear Folks: Now that the war is over, I can tell you something of my part in it during my tour of duty on the U.S.S. BUCYRUS VICTORY (AK-234). This ship has been commended by the Commander Amphibious Group Seven for the important role it played in the Okinawa Operation. We were up there twice, once at the very beginning of the assault, and again when the suicidal resistance of the Japanese was at its height. We carried thousands of tons of ammunition to the anchorage in Kerama Retto, which is a small group of islands just west of Okinawa, and issued it to battleships, cruisers and destroyers. That cargo worried us a little ( to put it mildly ) during the 73 times we were at general quarters and Japanese Kamikaze planes were in the sky somewhere above us. From the very beginning our ship was designated an ammunition cargo ship. She and nine sister merchant ships were taken over from the U, S. Maritime Commission for the specific purposes of carrying ammunition to the fleet and issuing it to the fighting ships thereof. However, we did carry one load of general, non-explosive cargo. After commissioning at Richmond, California, and a brief shakedown at San Pedro, California, the ship was loaded at Port Hueneme with a general cargo which we took to Pearl Harbor and discharged there.
