“…1995, Yokoyama et al 2000, with a gradual sea level rise to approximately 150 m (Larcombe et al 1995). As sea levels gradually increased, coral atolls and cays were formed along the length of the Great Barrier Reef (Australia), opening up suitable breeding habitat for pelagic seabirds such as sooty terns (Mclean et al 1978, Beaman et al 1994, Baker and Haworth 1997. The estimate of population expansion from sooty tern sequences sampled from the south-western Pacific (i.e.…”

Peck, D. R. and Congdon, B. C. 2004. Reconciling historical processes and population structure in the sooty tern Sterna fuscata. Á/ J. Avian Biol. 35: 327 Á/335.To test the influence of past vicariant events on population genetic structure of the sooty tern Sterna fuscata , we examined sequence variation in the mitochondrial control region of individuals from the Indo-Pacific and Atlantic Oceans. Our analyses indicate a rapid population expansion at a global scale during the last 100 000 years, consistent with global recolonisation during the interstade following the Pleistocene glacial maxima (125 000 Á/175 000 years bp). We estimate islands of the Great Barrier Reef and Coral Sea were colonised no more than 16 000 years ago, most likely in association with the appearance of new breeding habitat following the final Pleistocene glacial retreat (19 000 Á/22 000 years bp). Our results suggest that ice sheets linked to major glacial events not only impact genetic structuring in temperate seabirds, but that sea level changes in the tropics associated with these same events have also significantly impacted contemporary genetic structuring in tropical seabird species.

An infilled wetland located behind coastal dunes in north-east Northland is used to reconstruct a local history of environmental change spanning early Holocene (c. 7000 yr BP) to modern time. Proxy indicators (sediment texture, diatoms and pollen) provide evidence for a transition from marginal marine-to brackish-to freshwaterconditions in the wetland. Radiocarbon ages constrain the chronology of this succession to 7880-7430 cal. yr BP for the early period of marine conditions, 3570-3210 cal. yr BP for the latter brackish phase and 1060-800 cal. yr BP for the change to freshwater conditions. Within this succession, the diatom record preserves a strong brackish signal at core depths above the limit of the modern tidal range. This is presented as preliminary evidence for a mid-Holocene sea level highstand for northern New Zealand of approximately 1.2 m above present mean sea level. Keywords diatoms;14 C dating; highstand; palynology; sea level; sediments; stratigraphy INTRODUCTIONThe characteristics of sedimentary successions that constitute the coastal depositional record are controlled by the interplay between sea level, sediment supply and accommodation space. Studies of the facies that comprise these sedimentary successions traditionally focus on shoreface, beach and dune environments and associated marine-dominated processes (e.g., Curray 1964;Kraft 1971; Thorn 1983;Davis & Clifton 1987;Roy et al. 1994). In general, these particular environments do not always preserve a detailed record of environmental change in adjacent terrestrial systems. In contrast, back-barrier environments (wetlands, swamps, marshes and lagoons) do have the potential to record details of environmental change in both coastal and terrestrial systems, particularly responses to sea-level change .For the New Zealand coast, there has been little effort to use back-barrier environments to study environmental change, nor to resolve Holocene sea-level history beyond that established by Gibb (1986). Noticeably absent has been any attempt to establish evidence for a midHolocene highstand in sea level, a phenomenon now well documented for other coasts in the SW Pacific (e.g., Woodroffe et al. 1995;Baker & Haworth 1997Nunn 1998; Sloss et al. in press). This paper addresses these matters via a case study of a back-barrier wetland in northern New Zealand. The study objectives are to investigate the sensitivity of the wetland to marine and terrestrial influences, and to test for evidence of a sea-level highstand using a multiproxy analysis of the sediment record.

“…Samples for radiocarbon dating were restricted to either prograded coastal deposits or coralreef-flat formations, as the use of samples from different forms of evidence had led to a wide variation in results (Chappell et al, 1982, p. 82). It was for this reason that our work is based on a few fixed indicators from the intertidal zone, with tightly constrained zonation, as determined by well-researched biological mapping (Dakin, 1987; see also Baker and Haworth, 1997). Carbon-14 ages derived from the same type of sample, rather than a mix of different ones, are regarded as more Nakada and Lambeck (1989) Fig.…”

Haworth, R. J., Baker, R. G. V. and Flood, P. G. 2002. Predicted and observed Holocene sea-levels on the Australian coast: what do they indicate about hydro-isostatic models in far-field sites?.ABSTRACT: Data relating to Holocene sea-level elevations and ages, obtained by radiocarbon dating of relict calcareous skeletons of intertidal organisms from widely spaced parts of the Australian coast, a far-field region of comparative tectonic stability, are divisible into two sets, namely: pre-and post-ca. 3600 yr BP. The older ages are from material consistently between 1.5 m and 2.2 m higher than present sea-level, whereas the younger ages (ca. 3600-1500 yr BP) generally cluster around 1 m above present sea-level. The elevations do not display any decline in amplitude from north to south over an extensive transect, contrary to predictions by hydro-isostatic models. Also, there appears to be little difference between time-elevation results for the coasts of North Queensland, New South Wales and the Bass Strait region adjacent to Tasmania, despite differences in the width of the continental shelf in these three locations, and the expectation of some hydro-isostatic warping of the continental shelf subsequent to the onset of the Holocene transgression. Results from the south and southwest coasts of Western Australia also display similar elevations to the east coast for the same time periods. There is sufficient evidence extending over 20°of latitude to suggest that north-south differences related to hydro-isostatic influence is limited or non-existent. There is insufficient data to test hydro-isostatic models across continental shelves. Hydro-isostasy, and the lithological elasticity it reflects, may not be as pronounced in far-field sites with narrow continental shelves as models predict. Stable far-field passive continental margins may be the best place to measure the ratio of inputs of eustatic and hydro-isostatic influences on Holocene relative sea-levels.
