Declines of Seagrasses in a Tropical Harbour, North Queensland, Australia, Are Not the Result of a Single Event
Declines of seagrasses in a tropical harbour, North Queensland, Australia, are not the result of a single event SKYE MCKENNA*, JESSIE JARVIS, TONIA SANKEY, CARISSA REASON, ROBERT COLES and MICHAEL RASHEED Centre for Tropical Water and Aquatic Ecosystem Research, James Cook University, Queensland, Australia *Corresponding author (Email, [email protected]) A recent paper inferred that all seagrass in Cairns Harbour, tropical north-eastern Australia, had undergone ‘complete and catastrophic loss’ as a result of tropical cyclone Yasi in 2011. While we agree with the concern expressed, we would like to correct the suggestion that the declines were the result of a single climatic event and that all seagrass in Cairns Harbour were lost. Recent survey data and trend analysis from an on-ground monitoring program show that seagrasses in Cairns Harbour do remain, albeit at low levels, and the decline in seagrasses occurred over several years with cyclone Yasi having little additional impact. We have conducted annual on-ground surveys of seagrass distribution and the above-ground meadow biomass in Cairns Harbour and Trinity Inlet since 2001. This has shown a declining trend in biomass since a peak in 2004 and in area since it peaked in 2007. In 2012, seagrass area and above-ground biomass were significantly below the long-term (12 year) average but seagrass was still present. Declines were associated with regional impacts on coastal seagrasses from multiple years of above-average rainfall and severe storm and cyclone activity, similar to other nearby seagrass areas, and not as a result of a single event.

NASA Sees Tropical Cyclone Jasmine Over Vanuatu and New Caledonia 9 February 2012
NASA sees Tropical Cyclone Jasmine over Vanuatu and New Caledonia 9 February 2012 circulation. Later on February 8 at 0600 UTC (1 a.m. EST), Cyclone Jasmine had maximum sustained winds near 115 knots (132 mph/213 kph). It was located near 20.6 South and 169.4 East, about 185 nautical miles (213 miles/~343 km) east-northeast of Noumea, New Caledonia. It was moving to the southeast at 12 knots (~14 mph/~22 kph). In Vanuatu, a blue alert was in effect on February 8 for the Tafea province and now only applies to Aneityum. Warnings in New Caledonia cover the entire territory until 6 a.m. local time, and are under a yellow pre-alert.

IPRC and Department of Meteorology, University of Hawaii, Honolulu, Hawaii 3. Research Institute for Global Change, JAMSTEC, Yokohama, Japan Abstract The effects of air-sea coupling over the tropical Indian Ocean (TIO) on the eastward- and northward-propagating boreal summer intraseasonal oscillation (BSISO) are investigated by comparing a fully coupled (CTL) and a partially decoupled Indian Ocean (pdIO) experiment using SINTEX-F coupled GCM. Air-sea coupling over the TIO significantly enhances the intensity of both the eastward and northward propagations of the BSISO. The maximum spectrum differences of the northward- (eastward-) propagating BSISO between the CTL and pdIO reach 30% (25%) of their respective climatological values. The enhanced eastward (northward) propagation is related to the zonal (meridional) asymmetry of sea surface temperature anomaly (SSTA). A positive SSTA appears to the east (north) of the BSISO convection, which may positively feed back to the BSISO convection. In addition, air-sea coupling may enhance the northward propagation through the changes of the mean vertical wind shear and low-level specific humidity. The interannual variations of the TIO regulate the air-sea interaction effect. Air-sea coupling enhances (reduces) the eastward-propagating spectrum during the negative Indian Ocean dipole (IOD) mode, positive Indian Ocean basin (IOB) mode and normal years (during positive IOD and negative IOB years). -
Caldonia”—Louis Jordan (1945) Added to the National Registry: 2013 Essay by Stephen Koch (Guest Post)*
“Caldonia”—Louis Jordan (1945) Added to the National Registry: 2013 Essay by Stephen Koch (guest post)* Louis Jordan Original label “Caldonia” film poster, 1945 “Caldonia” (originally titled “Caldonia Boogie”) became one of Louis Jordan and his Tympany Five’s most enduring hits. The song, with its lyrical catchphrase “Caldon-YAH! Caldon-YAH! What makes your big head so hard!?” set America on its ear and spawned endless cover versions, two of which competed directly with Jordan’s version in 1945. The song had been in Jordan’s repertoire since at least the summer of 1944, when he recorded it for use on a December airing of “Jubilee!,” an Armed Forces Radio Service show for African- American servicemen. In January, 1945 he recorded it for Decca, but the label first released a pairing of Jordan’s “Mop! Mop!” and “You Can’t Get That No More” that became a major hit that winter, and perhaps delayed the release of “Caldonia.” In February, Jordan filmed a performance of it for a short film of the same name, which hit theaters in March. In late Feburary, white bandleader Woody Herman recorded a modern jazz-tinged arrangement by Ralph Burns, who’d heard Jordan perform it live. Herman’s version hit the stores at about the time that African-American bandleader Erskine Hawkins recorded a version for RCA-Victor at the end of March. Decca, perhaps feeling the pressure, released Jordan’s definitive small group version at almost the same time that Hawkins’ disc came out in mid-April. Surprisingly, all three versions of the tunes were hits. -

It draws on my fieldwork in Noumea and Mare in the Loyalty Islands of New Caledonia. The main part of the thesis looks at the interactions of this group of young people with other ethnic and social groups living in New Caledonia. These include the Kanaks, the “Caldoches” (native-born Caledonians of French origin), the “Metros” (immigrants from metropolitan France), Pacific islanders, Vietnamese and Indonesians. The thesis also includes a short section describing Mare itself and my fieldwork there. Particular attention is paid to the Kanaks and to the Caldoches, whose rural and urban lifestyles are compared and contrasted to those of the young people being studied.
