Primary production is at the base of the marine food web and plays a central role for global biogeochemical cycles. Yet global ocean primary production is known to only a factor of ~2, with previous estimates ranging from 38 to 65 Pg C yr−1 and no formal uncertainty analysis. Here, we present an improved global ocean biogeochemistry model that includes a mechanistic representation of photosynthesis and a new observational database of net primary production (NPP) in the ocean. We combine the… 

Global ocean primary production trends in the modern ocean color satellite record (1998–2015)

Ocean primary production (PP), representing the uptake of inorganic carbon through photosynthesis, supports marine life and affects carbon exchange with the atmosphere. It is difficult to ascertain

Constraint on net primary productivity of the global ocean by Argo oxygen measurements

The biological transformation of dissolved inorganic carbon to organic carbon during photosynthesis in the ocean, marine primary production, is a fundamental driver of biogeochemical cycling, ocean

Primary Production, an Index of Climate Change in the Ocean: Satellite-Based Estimates over Two Decades

A global database of in situ measurements of photosynthesis versus irradiance (P-I) parameters and a 20-year record of climate quality satellite observations were used to assess global primary production and its variability with seasons and locations as well as between years.

Net primary productivity estimates and environmental variables in the Arctic Ocean: An assessment of coupled physical-biogeochemical models

iNPP model skill was constrained by different factors in different Arctic Ocean regions, and better parameterization of biological and ecological microbial rates are needed for improved Arctic Ocean biogeochemical modeling.

Variability in the Global Ocean Carbon Sink From 1959 to 2020 by Correcting Models With Observations

The ocean reduces human impact on the climate by absorbing and sequestering CO2. From 1950s to the 1980s, observations of pCO2 and related ocean carbon variables were sparse and uncertain. Thus,

Can Rates of Ocean Primary Production and Biological Carbon Export Be Related Through Their Probability Distributions?

A theory for interpreting measurements of two key biogeochemical fluxes—primary production by phytoplankton and biological carbon export from the surface ocean by sinking particles—in terms of their probability distributions is described, informed by the lognormality of both p and f, to derive a linear relationship between the log‐moments of their distributions.

Reviews and syntheses: Assessment of Biogeochemical Models in the Marine Environment

Abstract. Marine biogeochemical models are key tools utilized to quantify numerous aspects of biogeochemistry including primary productivity, cycling of nutrients, redistribution of plankton, and

Consistency and Challenges in the Ocean Carbon Sink Estimate for the Global Carbon Budget

Based on the 2019 assessment of the Global Carbon Project, the ocean took up on average, 2.5 ± 0.6 PgC yr−1 or 23 ± 5% of the total anthropogenic CO2 emissions over the decade 2009–2018. This sink

On modeling the Southern Ocean Phytoplankton Functional Types

Abstract. This study highlights recent advances and challenges of applying coupled physical-biogeochemical modeling for investigating the distribution of the key phytoplankton groups in the Southern

Marine biogeochemical cycling and oceanic CO2 uptake simulated by the NUIST Earth System Model version 3 (NESM v3)

Abstract. In this study, we evaluate the performance of the Nanjing University of Information Science and Technology (NUIST) Earth System Model version 3 (hereafter NESM v3) in simulating the marine



Export Production in the Equatorial and North Pacific Derived from Dissolved Oxygen, Nutrient and Carbon Data

A global ocean inverse model that includes the 3D ocean circulation as well as the production, sinking and remineralization of biogenic particulate matter is used to estimate the carbon export flux

Ocean biogeochemical response to phytoplankton‐light feedback in a global model

Oceanic phytoplankton, absorbing solar radiation, can influence the bio-optical properties of seawater and hence upper ocean physics. We include this process in a global ocean general circulation

Carbon‐based ocean productivity and phytoplankton physiology from space

Compared to an earlier chlorophyll-based approach, carbonbased values are considerably higher in tropical oceans, show greater seasonality at middle and high latitudes, and illustrate important differences in the formation and demise of regional algal blooms.

An estimate of global primary production in the ocean from satellite radiometer data

An estimate of global net primary production in the ocean has been computed from the monthly mean near-surface chlorophyll fields for 1979-1986 obtained by the Nimbus 7 CZCS radiometer. Our model

Ecosystem dynamics based on plankton functional types for global ocean biogeochemistry models

Ecosystem processes are important determinants of the biogeochemistry of the ocean, and they can be profoundly affected by changes in climate. Ocean models currently express ecosystem processes

Primary production of the biosphere: integrating terrestrial and oceanic components

Integrating conceptually similar models of the growth of marine and terrestrial primary producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of carbon per year, with

Biogeochemical fluxes through mesozooplankton

Mesozooplankton are significant consumers of phytoplankton, and have a significant impact on the oceanic biogeochemical cycles of carbon and other elements. Their contribution to vertical particle
