bulloides d'Orbigny as indices of water masses," Antarctic Journal, vol.
The species differs from Globigerinoides tenellus and Globigerinoides ruber in having a more lobulate periphery and in the absence of supplementary apertures; and from other Globigerina
species in having a coarsely perforate wall.
One of the major factors causing erosion is salt, which is absorbed by the porous globigerina
and then breaks open the rock when it crystallises inside.

They are gray to green and contain benthic (miliolids, Nummulites, Neorotalia, Elphidium, Operculina, Amphistegina and textularids) and planktonic (Paragloborotalia mayeri and Globigerina
bulloides, Globigerinella calida (Parker, 1962) y N.
Also, the number of marine microorganisms in seafloor sediment--in particular, that of a species called Globigerina
bulloides--indicates the upwelling of nutrient-rich waters, another measure of wind shear at the ocean's surface.
In cores 25-1 and 25-2 I have recognized Bolli's Quaternary Globorotalia crassaformis viola, Globorotalia crassaformis hessi, Globigerina
calida calida, Globigerina
bermudezi, and Globorotalia fimbriata Subzones (Bylinskaya et al., 2002).
Tanner (1835-1906) was making familiar entries of salps, foraminifera, globigerina
, large red crabs, starfish, squid, "coral growth," barnacles, and lobsters, reflecting the growing interest of all in that portion of the harvest.
She has found that the isotopic composition of two species, Globigerina
bulloides and Globigerinoides ruber, accurately records sea surface temperature changes in Guaymas Basin [ILLUSTRATION OMITTED].
The planktic foraminifera include genera of Globorotalia Globigerina
andPlanorotalites and their abundance ranges from 10 to 20 % of the total allochems.
