ABSTRACT The North Pacific Subtropical Gyre (NPSG) is the largest ecosystem on our planet. However, this expansive habitat is also remote, poorly sampled, and therefore not well understood. For example, the most abundant oxygenic phototroph in the NPSG, Prochlorococcus, was described only a decade ago. Other novel Bacteria, Archaea and Eukarya, recently identified by nucleic acid sequence analysis, have not been isolated. In October 1988, an ocean time-series research program was established to… 
Ecosystem Structure and Dynamics in the North Pacific Subtropical Gyre: New Views of an Old Ocean
TLDR
A revised paradigm is built on the strength of high-quality time-series observations, on insights from the application of state-of-the-art –omics techniques and, more recently, the discoveries of novel microorganisms and metabolic processes.
Microbial dynamics and biogeochemistry in the North Pacific Subtropical Gyre
The research presented in this dissertation describes the influence of planktonic bacteria on upper ocean organic matter dynamics in the North Pacific Subtropical Gyre (NPSG). Analyses of the
Increasing subtropical North Pacific Ocean nitrogen fixation since the Little Ice Age
TLDR
Records of bulk and amino-acid-specific 15N/14N isotopic ratios preserved in the skeletons of long-lived deep-sea proteinaceous corals collected from the Hawaiian archipelago are analysed and it is found that the isotopic mass balance between nitrate and nitrogen fixation implies a 17 to 27 per cent increase in nitrogen fixation over this time period.
Nitrogen fixation in an anticyclonic eddy in the oligotrophic North Pacific Ocean
TLDR
Examination of spatial variations in upper ocean nutrient inventories, N2 fixing microorganism diversity and abundance, and rates of N2 fixation in an anticyclonic eddy near Station ALOHA in the North Pacific Subtropical Gyre suggests that mesoscale physical variability can play an important role in modifying the abundances of N 2 fixing microorganisms and associated rates ofN2 fixationIn open ocean ecosystems.
Millennial-scale plankton regime shifts in the subtropical North Pacific Ocean
TLDR
High-resolution records of changing plankton community composition in the North Pacific Ocean over the past millennium revealed three major plankton regimes corresponding to Northern Hemisphere climate periods, which are characterized by increasing production by dinitrogen-fixing cyanobacteria.
Broad-scale trophic shift in the pelagic North Pacific revealed by an oceanic seabird
TLDR
The amino acid records do not support a broad-scale increase in nitrogen fixation in the North Pacific subtropical gyre, and suggest that the food web structure in the NPO has shifted at a broad geographical scale, a phenomenon potentially related to industrial fishing.
Local stratification control of marine productivity in the subtropical North Pacific
[1] Strengthened stratification of the upper ocean due to global warming is generally expected to inhibit marine primary productivity in the subtropics, based on the supposition that increased water

TLDR
This Central Pacific Study has its roots in the California Cooperative Oceanic Fisheries Investigations (CalCOFI), an interagency study originally established to understand the disappearance of the sardines from the California Current.
