Chlorophylls and carotenoids are commonly used as quantitative biomarkers for the
composition and biomass of marine phytoplankton. This chapter provides an overview of the …

Error-quantified, synoptic-scale relationships between chlorophyll-a (Chl-a) and
phytoplankton pigment groups at the sea surface are presented. A total of ten pigment …

Since the start of the industrial revolution, human activities have caused a rapid increase in
atmospheric carbon dioxide (CO 2) concentrations, which have, in turn, had an impact on …

One of the first comparisons of a natural iron fertilized bloom with a high‐nutrient low‐
chlorophyll (HNLC) site was undertaken during the Kerguelen ocean and plateau compared …

To investigate the factors regulating the concentration of particulate iodine (PI) in seawater, it
was measured in two Pacific coastal areas adjacent to Japan (offshore Aomori and offshore …

The response of heterotrophic bacteria (Bacteria and Archaea) to the spring phytoplankton
bloom that occurs annually above the Kerguelen Plateau (Southern Ocean) due to natural …

Bacteria, archaea and other microbes have dominated most biogeochemical processes on
Earth for> 99% of the history of life, but within the past few decades anthropogenic activity …

Organic carbon (C) and total nitrogen (N) contents and corresponding isotope ratios were
determined in surficial sediment (0–3 cm) at 94 stations ranging from 21 to 1995 m water …

The subarctic Pacific is generally perceived as relatively homogeneous since the North
Pacific Subpolar Gyre dominates the water circulation in the area. However, previous …

This study assesses the response of phytoplankton assemblages to recent climate change,
especially with regard to the shrinking of sea ice in the northern Chukchi Sea of the western …
