We compiled and analyzed 101 accessiblereports of 194 individual Kirtland’s Warblers (Dendroica kirtlandii) from the Bahama Archipelago, 1841-1997. Most individuals were reportedfrom northernislands (88%), and most sightreports (84%) and specimen/banding records(76%) were on island groupsthat supportor formerly supportedopen woodlandsof Caribbeanpine (Pinus curilxzea). Where habitat descriptionswere provided, 60% mentioned specificallypines or pine understory.After analysesfor potentialbiases from misidentification in sight reports and unequaleffort acrossislands, we found no evidence to supportprevious claims that Kirtland’s Warblersprefer scrubor avoid pine habitats.Rather, based upon 1995- 1997 winter surveysusing acoustic broadcasts, K&land ’s Warblerswere detectedin pine wood- landsof Abaco and Grand Bahamamore frequentlythan expectedcompared to encounterrates generatedby a null model of random habitatuse.

The Free National Movement won seven seats and independents won four seats. The PLP had been out of power since 1992 when the FNM defeated them for the first time since the independence of The Bahamas. They had been in power for 25 years under the leadership of Sir Lynden O. Pindling. They now have won 21 of the 24 Nassau seats, three of the six Grand Bahama seats and five of the seats in the other Family Islands. Two candidates who had previously been cabinet ministers in the FNM government ran independently and won. They were Mr. Pierre Dupuch, former Minister of Agricul- ture and Fisheries, and Mr. Tennyson Well, former Attorney General. Mr. Christie was sworn in on May 3 in a ceremony of pomp and pageantry at Govern- ment House. He pledged to “build a peace- ful, prosperous and just society for all our people.” He is the third prime minister since The Bahamas became an independent coun- try in 1973.

SEDIMENTARY FRAMEWORK of Lmainland FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA
GREAT BARRIER REEF MARINE PARK AUTHORITY TECHNICAL MEMORANDUM GBRMPA-TM-14 SEDIMENTARY FRAMEWORK OF lMAINLAND FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA D.P. JOHNSON and RM.CARTER Department of Geology James Cook University of North Queensland Townsville, Q 4811, Australia DATE November, 1987 SUMMARY Mainland fringing reefs with a diverse coral fauna have developed in the Cape Tribulation area primarily upon coastal sedi- ment bodies such as beach shoals and creek mouth bars. Growth on steep rocky headlands is minor. The reefs have exten- sive sandy beaches to landward, and an irregular outer margin. Typically there is a raised platform of dead nef along the outer edge of the reef, and dead coral columns lie buried under the reef flat. Live coral growth is restricted to the outer reef slope. Seaward of the reefs is a narrow wedge of muddy, terrigenous sediment, which thins offshore. Beach, reef and inner shelf sediments all contain 50% terrigenous material, indicating the reefs have always grown under conditions of heavy terrigenous influx. The relatively shallow lower limit of coral growth (ca 6m below ADD) is typical of reef growth in turbid waters, where decreased light levels inhibit coral growth. Radiocarbon dating of material from surveyed sites confirms the age of the fossil coral columns as 33304110 ybp, indicating that they grew during the late postglacial sea-level high (ca 5500-6500 ybp). The former thriving reef-flat was killed by a post-5500 ybp sea-level fall of ca 1 m. Although this study has not assessed the community structure of the fringing reefs, nor whether changes are presently occur- ring, it is clear the corals present today on the fore-reef slope have always lived under heavy terrigenous influence, and that the fossil reef-flat can be explained as due to the mid-Holocene fall in sea-level. -

Key agents in this shaping have been the calcium carbonate-fixing biota that have constructed the ocean- facing fringing reefs and produced the extensive backreef sediments that form the limestone platforms, cliffs and terraces that characterise these coasts. Today’s reefs comprise tough, algal- clad intertidal bars composed largely of coral rubble derived from their ocean front. They provide protection from wave attack to the inshore platforms with their sediment veneers and their beach and beach plain sands that are susceptible to erosion. If the eastern African coasts are subjected to the rise of sea-level that is predicted at the global scale during the coming century, the protective role of the reef bars will be diminished if their upward growth fails to keep pace. Favourable ocean temperatures and restraint in the destructive human pressures impacting the reef ecosystems will facilitate such growth. INTRODUCTION limestones).

Further evidence that erosion has at least processes operating to shape it. The canyon has kept the valleys open as the Bahama Banks grew two major branches, one following Northwest comes from the winding courses and the numerous Providence Channel and the other the Tongue of tributaries that descend the walls from the shallow the Ocean, which join 15 mi north of New Provi- Banks, particularly on the south side of Northwest dence Island, and continue seaward as a submarine Branch.

Transport, Potential Vorticity, and Current/Temperature Structure Across Northwest Providence and Santaren Channels and the Florida Current Off Cay Sal Bank
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 100, NO. C5, PAGES 8561-8569, MAY 15, 1995 Transport, potential vorticity, and current/temperature structure across Northwest Providence and Santaren Channels and the Florida Current off Cay Sal Bank Kevin D. Leaman,' PeterS. Vertes, 1 Larry P. Atkinson,2 Thomas N. Lee,' Peter Hamilton,3 and Evans WaddelP Abstract. Currents and temperatures were measured using Pegasus current profilers across Northwest Providence and Santaren Channels and across the Florida Current off Cay Sal Bank during four cruises from November 1990 to September 1991. On average, Northwest Providence (1.2 Sv) and Santaren (1.8 Sv) contribute about 3 Sv to the total Florida Current transport farther north (e.g., 27°N). Partitioning of transport into temperature layers shows that about one-half of this transport is of" 18°C" water (17°C-19.SOC); this can account for all of the "excess" 18°C water observed in previous experiments. This excess is thought to be injected into the 18°C layer in its region of formation in the northwestern North Atlantic Ocean. Due to its large thickness, potential vorticities in this layer in its area of formation are very low. In our data, lowest potential vorticities in this layer are found on the northern end of Northwest Providence Channel and are comparable to those observed on the eastern side of the Florida Current at 27°N. On average a low-potential-vorticity l8°C layer was not found in the Florida Current off Cay Sal Bank. 1. Introduction the Florida Current/Gulf Stream cross-stream structure was carried out using Pegasus profiler data at 27°N as well as at Because of its importance to the overall general circula 29°N and off Cape Hatteras [Leaman et al., 1989]. -
