Cruise track and oceanographic setting. Specimens of planktonic foraminifera were collected at nine stations along a north/south cruise transect in the central Arabian Sea (20° N/64°E° S/56°E) during the summer monsoon of late June/July (Figure (Figure1A; 1A; cruise Charles Darwin CD, NERC).The oceanography of the Arabian Sea during the SW monsoon is shown in. Coral reefs and lagoons of the western Pacific Ocean contain extremely diverse assemblages of benthic foraminifera [9, 44, 60, 66]. The reefal environments of Moorea also harbor particularly diverse assemblages of benthic foraminifera that rival those found elsewhere in the Indo-Pacific except for the absence of certain large symbiont-bearing taxa.

This effect would be most likely to occur in midsummer, a time when tropical to subtropical foraminifera would find it easier to. middle Eocene; – Ma) tropical temperatures, using planktonic foraminifera belonging to the genus Morozovella from Ocean Drilling Program Site on Allison Guyot (western central equatorial Pacific Ocean).

These dominant taxa belong to the informal ‘Larger Benthic Foraminifera’ group; heavily calcified taxa typical of tropical reefs throughout the Paci There are a large number of rare taxa (74 taxa.

  Here, we present data from individual measurements of Mg/Ca in two species of planktic foraminifera, surface dwelling Globigerinoides ruber and thermocline dwelling Neogloboquadrina dutertrei, from nine core tops across the equatorial Pacific (n ≈ 70 per core for each species).

Foraminifera (/ f ə ˌ r æ m ə ˈ n ɪ f ə r ə /; Latin for "hole bearers"; informally called "forams") are single-celled organisms, members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell (called a "test") of diverse forms and of chitin (found in some simple genera.

In the tropical Central and West Pacific as well as in the East Indian Ocean, symbiont-bearing benthic foraminifera often are the main producers of calcium carbonate grains deposited at beaches.

The proportion of foraminiferal tests in medium-sized to coarse sand grains may range from 20% to 95%. The flux of planktonic foraminifera between μm and 1 mm to the seafloor has been estimated for the central Pacific (abyssal plain east of Hawaii) and the tropical Atlantic (Demerara Abyssal Plain) based on sediment trap samples collected from various water depths.

BP (Conroy et al., Symbiont-bearing benthic foraminifera are restricted to the euphotic zone of tropical and warm-temperate seas.

Species distribution is correlated with depth, and the continuous alteration of community structures represents a coenocline. We investigated benthic foraminiferal species as tracers for carbon export flux in the Indo-Pacific warm pool (International Ocean Discovery Program Expedition ).

In core tops, the distribution of lower bathyal and upper abyssal species can be separated into two distinct groups. Shallow-Water Foraminifera and Other Microscopic Biota of Clipperton Island, Tropical Eastern Pacific The recent foraminiferal fauna and associated microbiota of Clipperton Island (°N, °W) were investigated at 20 sites collected in the intertidal zone around the perimeter of the island and from the edge of the inner brackish.

By: mateh [1] Optimal use of Mg/Ca as a paleotemperature proxy requires establishing calibrations for different species of foraminifera and quantifying the influence of dissolution. To achieve this goal, we have measured Mg/Ca and δ 18 O in a series of tropical and subtropical core tops, including four depth transects: the Ceara Rise, the Sierra Leone Rise, and the Rio Grande Plateau in the Atlantic.

Foraminifera or forams, as they are called, are an important group of tiny single-celled rhizarian are mostly marine, though a few live in fresh-water, and even on damp land the sea, they live both in the plankton (), and in the deeper water (the benthos).They have tests (like shells) made of calcium carbonate (CaCO 3).

Due to its plate tectonic setting, much of the coast­ line of the eastern margin of the Pacific Ocean is rugged.

Climatically it includes northern, central and southern wet zones with dry zones in between (see Fig. The principal surface-water currents are eastern boundary currents which.

Using this method, one finds that there were two major cycles of warming in which the limits of the tropical faunas extended significantly beyond the degree parallel.
