“…The deeply submerged and northward-sloping morphology of the banktop of Pedro Bank (Dolan 1972;Triffleman et al 1992) contrasts with the Great Bahama Bank. In addition, the high abundance of Halimeda growing on the top and margins of Pedro Bank Hine et al 1988;Dullo 1997) is in contrast to the carbonate producing coralgal community observed on the Bahamas. As recognised in earlier studies of the Nicaragua Rise carbonate system (Glaser and Droxler 1993;Schwartz 1996;Duncan 1997;Cunningham 1998;Andresen 2000), this difference in sediment production may explain the dominance of the fine-grained neritic sediment deposited in the periplatform environment.…”

The sedimentological study of thirteen sediment cores from the periplatform setting surrounding Pedro Bank (Northern Nicaragua Rise, Caribbean Sea) shows that during the last 300 ka turbidite deposition is controlled by at least four factors: (1) late Quaternary sea level fluctuations, (2) prolific fine-grained sediment production and export resulting in oversteepening of the upper slope environment, (3) the proximity to the bank margin, and (4) local slope and seafloor morphology. The most intriguing finding of this study is the paucity of turbidites, with only 101 turbidites in 13 cores in this tectonically active setting near the Caribbean plate boundary. Throughout the last 300 ka, the frequency of turbidite input during interglacial stages is three times higher than during glacial stages. Also it is obvious that changes in sea level influence the timing of turbidite deposition. This is especially evident during the transgressions resulting in rapid renewed bank-top flooding, subsequent neritic sediment overproduction, and offbank export. The flooding event during each transgression is usually recorded by the onset of turbidite deposition at various sites along several platform-to-basin transects in down-and upcurrent slope settings. Overall, however, more turbidites are deposited during the regressive rather than the transgressive phases in sea level, probably as a result of sediment reorganisation on the slope resulting in slope failure. Five cores show "highstand bundling" of calciturbidites, i.e. higher number of turbidites during highstands than during lowstands in sea level.

“…Topographical upwelling causes elevated nutrient levels on the western Nicaragua Rise (Roberts and Murray 1983;Hine et al 1987;Hallock et al 1988;Triffleman et al 1992). The decreasing trophic resources from west to east are accompanied by a gradient in the association of carbonate producers .…”

“…Hallock and Schlager 1986). Carbonate sediment on the western platforms is produced by calcareous green algae such as Halimeda (Hine et al 1987), which makes the western Nicaragua Rise a chloralgal tropical carbonate system characterized by an absence of corals. This is in contrast to the well-developed coral reefs along the Jamaican coast on the eastern Nicaragua Rise.…”

Water temperature has received considerable attention as steering factor for the genesis of different types of marine carbonate sediments. However, parameters other than temperature also strongly influence ecosystems and, consequently, the carbonate grain associations in the resulting carbonate rock. Among those factors are biological evolution, water energy, substrate, water chemistry, light penetration, trophic conditions, CO 2 concentrations, and Mg/Ca ratios in the seawater. Increased nutrient levels in warm-water settings, for example, lead to heterotrophicdominated associations that are characteristic of temperate to cool-water carbonates. Failure to recognize the influence of such environmental factors that shift the grain associations towards heterotrophic communities in low latitudes can lead to misinterpretation of climatic conditions in the past. Modern analogues of low-latitude heterozoan carbonates help to recognize and understand past occurrences of heterozoan warm-water carbonates. Careful analysis of such sediments therefore is required in order to achieve robust reconstructions of past climate.

“…According to Suchy and West (2001), the growth of phylloid algae appears to coincide with high nutrient inputs, an interpretation supportive of our findings. Similarly, during the Holocene, the phylloid udoteacean alga Halimeda thrives and is known to build mounds (bearing certain similarities to the Palaeozoic phylloid algal mounds) in low-latitude areas of high nutrient levels, either from adjacent continental areas or from coastal settings influenced by upwelling Hine et al, 1988;Marshall and Davies, 1988;Roberts et al, 1988;Davies et al, 2004;Wilson and Vecsei, 2005).…”
