Special Issue Information

Dear Colleagues,

Paleoceanography has been emerged as an exciting scientific discipline since 1980 while ocean drilling into the sea floor provided plenty of marine sediment cores that were very useful for reconstructing past ocean history. Studies on paleoceanography have been also grown very rapidly to help understand long-term climate change as newly advanced observations, techniques, and modeling used in modern climatology provide excellent insights in interpreting past ocean history. Though studies on long-term ocean climate variability at orbital- to multi-decadal scales by the uses of marine sedimentary archives provide crucial information on how ocean dynamics link to Earth system evolution, compiling a global picture of past climate change requires terrestrial archives such as from ice cores, lake and loess sediment cores, and corals and stalagmites. This special issue, in the light of developing background of paleoceanography, encourages publications that help improve our understanding on the dynamics and interaction of complicated ocean-climate system. This special issue aims to collect recent new research into paleoceanography on the following themes: (1) new proxy record reconstructions for long-term ocean climate variability at orbital- to multi-decadal scales based on marine sediment cores; (2) regional to global data synthesis of high-resolution ocean climate records from marine, lake, cave, coral, and loess sediment archives; (3) new evaluation and calibration of paleoceanographic proxies by modern ocean observations such as stratified ocean water sampling, sediment traps, and surface sediment coring; (4) verifications on current conceptual models such as that involving long-term, North Atlantic Deep Water (NADW), Antarctic surface or bottom water formation, Intertropical Convergence Zone (ITCZ), Monsoon, or El Niño-Southern Oscillation (ENSO)-like mechanisms by reconstructed high-resolution paleoceanographic and paleoclimatic records and global climate models. The special issue also welcomes contributions for presenting new ideas for the last decade direction of paleoceanography, reviews on current status and problem, and possible new techniques that maybe useful in future paleoceanographic studies.

We examine the role of the vegetation cover and the associated hydrological cycle on the deep ocean circulation during the Late Miocene (~10 million years ago). In our simulations, an open Central American gateway and exchange with fresh Pacific waters leads to a weak and shallow thermohaline circulation in the North Atlantic Ocean which is consistent with most other modeling studies for this time period. Here, we estimate the effect of a changed vegetation cover on the ocean general circulation using atmospheric circulation model simulations for the late Miocene climate with 353 ppmv CO2 level. The Late Miocene land surface cover reduces the albedo, the net evaporation in the North Atlantic catchment is affected and the North Atlantic water becomes more saline leading to a more vigorous North Atlantic Deep Water circulation. These effects reveal potentially important feedbacks between the ocean circulation, the hydrological cycle and the land surface cover for Cenozoic climate evolution. Full article

Comparison of the Performance of Two Advanced Spectral Methods for the Analysis of Times Series in Paleoceanography

Many studies have revealed the cyclicity of past ocean/atmosphere dynamics at a wide range of time scales (from decadal to millennial time scales), based on the spectral analysis of time series of climate proxies obtained from deep sea sediment cores. Among the many techniques available for spectral analysis, the maximum entropy method and the Thomson multitaper approach have frequently been used because of their good statistical properties and high resolution with short time series. The novelty of the present study is that we compared the two methods by according to the performance of their statistical tests to assess the statistical significance of their power spectrum estimates. The statistical significance of maximum entropy estimates was assessed by a random permutation test (Pardo-Igúzquiza and Rodríguez-Tovar, 2000), while the statistical significance of the Thomson multitaper method was assessed by an F-test (Thomson, 1982). We compared the results obtained in a case study using simulated data where the spectral content of the time series was known and in a case study with real data. In both cases the results are similar: while the cycles identified as significant by maximum entropy and the permutation test have a clear physical interpretation, the F-test with the Thomson multitaper estimator tends to find as no significant the peaks in the low frequencies and tends to give as significant more spurious peaks in the middle and high frequencies. Nevertheless, the best strategy is to use both techniques and to use the advantages of each of them. Full article
