  • Preliminary Report Tropical Storm Bud 13 - 17 June 2000
    Preliminary Report Tropical Storm Bud 13 - 17 June 2000 Jack Beven National Hurricane Center 21 July 2000 a. Synoptic history The origins of Bud can be traced to a tropical wave that emerged from the coast of Africa on 22 May. The wave generated little convection as it moved across the Atlantic and Caribbean. The wave moved into the eastern Pacific on 6 June, but showed few signs of organization until 11 June when a broad low pressure area formed a few hundred miles southwest of Acapulco, Mexico. The initial Dvorak intensity estimates were made that day. Further development was slow, as the low exhibited multiple centers for much of 11-12 June. As one center emerged as dominant, the system became a tropical depression near 0600 UTC 13 June about 370 n mi south-southwest of Manzanillo, Mexico (Table 1). The depression became Tropical Storm Bud six hours later as it moved northwestward. Bud reached a peak intensity of 45 kt early on 14 June while turning north-northwestward. The peak intensity was maintained for 12 hr, followed by slow weakening due to a combination of increasing vertical shear and cooler sea surface temperatures. Bud passed just northeast of Socorro Island on 15 June as a 40 kt tropical storm. It weakened to a depression on 16 June as it slowed to an erratic drift about 70 n mi north of Socorro Island. Bud dissipated as a tropical cyclone on 17 June about 90 n mi north-northeast of Socorro Island; however, the remnant broad low persisted until 19 June.

  • Of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds
    B BIO VIEW Curator Notes From the Brink of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds In terms of conservation efforts, the Rio Grande Zoo is a rare breed in its own right, using its expertise to preserve and breed species whose numbers have dwindled to almost nothing both in the wild and in captivity. Recently, we took charge of a little over one-tenth of the entire world’s population of Socorro doves which have been officially extinct in the wild since 1978 and are now represented by only 100 genetically pure captive individuals that have been carefully preserved in European institutions. Of these 100 unique birds, 13 of them are now here at RGZ, making us the only holding facility in North America for this species and the beginning of this continent’s population for them. After spending a month in quarantine, the birds arrived safe and sound on November 18 from the Edinburgh and Paignton Zoos in England. Other doves have been kept in private aviaries in California, but have been hybridized with the closely related mourning dove, so are not genetically pure. History and Background Socorro doves were once common on Socorro Island, the largest of the four islands making up the Revillagigedo Archipelago in the East- ern Pacific ocean about 430 miles due west of Manzanillo, Mexico and 290 miles south of the tip of Baja, California. Although the doves were first described by 19th century American naturalist Andrew Jackson Grayson, virtually nothing is known about their breeding behavior in the wild.

FARMERI, MARIA C. FARMER2 and RAINER BERGER3 ABSTRACT. Extensive eruptions of alkalic basalt from low-elevation fissures and vents on the southern flank of the dormant volcano, Cerro Evermann, accompanied the most recent phase of volcanic activity on Socorro Island, and created 14C the Lomas Coloradas, a broad, gently sloping terrain comprising the southern part of the island. We obtained ages of 4690 ± 270 BP (5000-5700 cal BP) and 5040 ± 460 BP (5300-6300 cal BP) from lacustrine deposits that occur within volcanic sequences of the lower Lomas Coloradas. Apparently, the sediments accumulated within a topographic depression between two scoria cones shortly after they formed. The lacustrine environment was destroyed when the cones were breached by headward erosion of adjacent stream drainages.

This paper presents the first record of “O.” rubescens from the tropical Mexican Pacific. Twelve octopuses were studied; 10 were collected in tide pools from five localities and two mature males were caught by fishermen in Oaxaca. We used mor- phometric characters and anatomical features of the digestive tract to identify the species. The five localities along the Mexican Pacific coast provide solid evidence that populations of this species have become established in tropical waters.

Teachers are strongly encouraged to adapt activities included in this guide to meet the specific needs of the grades they teach and their students. Activities developed for this guide support Next Generation Science Standards (NGSS), Ocean Literacy Principles, National Geography Standards and Common Core Language Arts (see page 27 for a standards alignment chart). An extraordinary journey into the mysterious world of one of nature’s most awe-inspiring marine mammals, Humpback Whales takes audiences to Alaska, Hawaii and the remote islands of Tonga for an immersive look at how these whales communicate, sing, feed, play and take care of their young. Captured for the first time with IMAX® 3D cameras, and found in every ocean on earth, humpbacks were nearly driven to extinction 50 years ago, but today are making a steady recovery. Join a team of researchers as they unlock the secrets of the humpback and find out what makes humpbacks the most acrobatic of all whales, why they sing their haunting songs, and why these 55-foot, 50-ton animals migrate up to 10,000 miles round-trip every year.

Avila National Hurricane Center 20 September 2016 GOES 15 SATELLITE IMAGE AT 0000 UTC 27 JULY SHOWING THE EYE OF FRANK AT THE TIME THE HURRICANE REACHED ITS PEAK INTENSITY. IMAGE COURTESY OF THE NAVAL RESEARCH LABORATORY. Frank was the fifth hurricane to form in the eastern North Pacific basin during July of 2016, marking a new record for this month. Frank produced sustained tropical-storm- force winds on Socorro Island. Hurricane Frank 2 Hurricane Frank 21 – 28 JULY 2016 SYNOPTIC HISTORY Frank’s origin was associated with a large-amplitude tropical wave that moved off of the west coast of Africa on 10 July. The wave travelled westward across the tropical Atlantic with little thunderstorm activity, and reached the western Caribbean Sea on 18 July. On 19 July, upper-air data from Central America showed that the wave had a well-defined mid-level circulation while the convection was increasing. The wave continued westward and its associated cloudiness and thunderstorms gradually became better organized on 20 July just south of the Gulf of Tehuantepec. The formation of a tropical depression occurred at 0600 UTC 21 July about 250 n mi south of Manzanillo, Mexico. The “best track” chart of the tropical cyclone’s path is given in Fig. 1, with the wind and pressure histories shown in Figs. 2 and 3, respectively. The best track positions and intensities are listed in Table 11. The cloud pattern continued to become better organized, and by 1200 UTC 21 July, the system was a tropical storm.

Tag data provide a unique view on individual movement patterns, at different scales than shipboard surveys, and have been used to discover new habitat areas, characterize oceanographic features, and delineate stock struc- tures, among other purposes. Due to the necessity for small tag-to-body size ratio, tags have largely been deployed on adult animals, resulting in a relative paucity of data on earlier life his- tory stages.
