Here you can access ocean net primary production (NPP) data for alternative NPP algorithms and using either SeaWiFS, MODIS or VIIRS data. You will also find visual comparisons of NPP algorithm products at different temporal scales (e.g., annual, monthly), brief descriptions of each algorithm, and code for your own algorithm implementation.

2023年2月1日 · In this review, we highlight historical milestones in the evolution of NPP modeling from an ocean color satellite perspective. We present a limited synthesis of contemporary global NPP model output to document basic spatial and temporal patterns in the satellite NPP record and related scientific findings in the literature.

Alternate NPP Products. The NPP Products path provides ocean productivity estimates for different satellite data sets, for 'standard' and 'alternative' productivity algorithms.

This absorption-based model exploits advances in ocean color inversion algorithms to define the inherent optical properties (IOPs) of the water, and thus defines NPP as a product of energy absorption (QPAR; derived from irradiance and the sum of phytoplankton absorption, af, relative to total absorption) and the quantum efficiency of growth ...

2023年10月31日 · Phytoplankton NPP is strongly influenced by the physico-chemical conditions of the ocean, including light, temperature, and nutrient availability.

2022年9月14日 · Here, we collate the most comprehensive dataset of wild seaweed NPP measurements to date and model area-based seaweed productivity rates across the coastal ocean. Compiled NPP measurements cover more than 400 unique sampling sites distributed across all ocean realms (fig. S1), spanning seaweed …

2021年11月24日 · Ocean net primary production (NPP) results from CO 2 fixation by marine phytoplankton, catalysing the transfer of organic matter and energy to marine ecosystems, supporting most marine food webs, and fisheries production …

2020年6月8日 · We examine the main drivers of marine NPP in the global ocean in order to understand why NPP is more predictable in some regions than in others. We further focus on NPP predictability within the world's LMEs in order to assess potential predictability in societally relevant regions.

2021年1月8日 · Net primary production (NPP) is the foundation of the oceans’ ecosystems and the fisheries they support. In the Arctic Ocean, NPP is controlled by a complex interplay of...

2006年12月7日 · Satellite measurements of ocean colour provide a means of quantifying ocean productivity on a global scale and linking its variability to environmental factors. Here we describe global ocean...
