Alve, E. (1991).Benthic foraminifera in sedimentcores reflecting heavy-metal pollution in Sorfjord, Western
Norway. Journal of Foraminiferal Research, 21(1): 1-19.
From abstract: Analysis of benthic foraminifera in two short sediment cores (15 and 53 m water depth) from
heavy metal-polluted Sorfjord indicates that a faunal shift has taken place, due to heavy metal enrichment.
Both cores reveal an upward transition from a moderately pollutedenvironment represented by a
Verneuilina media assemblage to an extremely polluted environment represented by an Eggerelloides
scabrus assemblage. The total abundance of foraminifera decreases upward in both cores, whereas species
diversity shows only a minor decrease. The frequent occurrence of abnormal and pyritized specimens is
attributed to the effects of pollution. Seven different modes oftest deformation are described.
Alve, E. (1995). Benthic foraminiferal responses to estuarine pollution: a review. Journal of Foraminiferal
Research, 25(3): 190-203.
From abstract: Benthic foraminiferal distributions in polluted marine areas have been investigated over the last
three to four decades, and several workers have pointed out that they provide one of the most sensitive andinexpensive markers available for indicating deterioration of marginal marine environments. Most
investigations have been carried out in temperate regions, in areas exposed to several pollution sources.
Environments characterized by organic waste contamination (e.g., sewage or paper and pulp mills) have been
addressed more frequently than areas exposed to oil, thermal and various other kinds ofpollution. Pollution
effects on the biota in estuaries can best be evaluated by comparing the natural, pre-pollution assemblages
with those of the present day. The presence of empty foraminiferal tests in sediment cores penetrating through
contaminated intervals provides this kind of information, but possible diagenetic alterations of the original
assemblages must always be considered.
Alve, E.(1995). Benthic foraminiferal distribution and recolonization of formerly anoxic environments in
Drammensfjord, Southern Norway. Marine Microplaeontology 25(2-3): 169-186.
From abstract: Investigations of living (stained) benthic foraminifera in the surface (0-1 cm) sediments along a
depth transect in Drammensfjord, southern Norway, have been carried out on samples collected in 1984 and
duringall four seasons in 1988. The transect runs through strongly variable environments from a well
oxygenated, brackish surface layer to anoxic waters of slightly less than normal marine salinity. The objectives
were to study foraminiferal recolonization patterns after a prolonged period (> 5 years) of nearly permanent
anoxic bottom water conditions in the lower parts of the transect, the seasonalstability of the assemblages
after recolonization, and interspecific tolerances to various environmental parameters (i.e., temperature,
salinity, dissolved oxygen concentration, water depth).

surface sediments: 1937 (Hoglund) and 1992/1993 data compared. Marine Micropaleontology, 25(4):269288.
From abstract: Both living (stained) and dead (unstained) foraminiferal assemblages from surface sediments
(0-2 cm) in the northwestern part of the Skagerrak have been studied in order to (1) define and characterize
the distribution of various modern benthic environments and (2) by comparing these findings with surface
samples collected 40-60 years ago, to document possible faunal changes...
