A Model for Nitrogen Fixation in the Presence of Ammonium
Former MIT Darwin Group member Keisuke Inomura, working with MIT CBIOMES investigator Mick Follows, presents a new quantitative model of nitrogen fixation in the presence of ammonium. Continue reading “A Model for Nitrogen Fixation in the Presence of Ammonium”
Study: Much of the surface ocean will shift in color by end of 21st century
Climate-driven changes in phytoplankton communities will intensify the blue and green regions of the world’s oceans. New work from CBIOMES researchers Stephanie Dutkiewicz and Oliver Jahn. Continue reading “Study: Much of the surface ocean will shift in color by end of 21st century”
Trends in Mediterranean Phytoplankton Phenology from Ocean-Color
by Helen Hill for CBIOMES
Changes in phytoplankton Chlorophyl (Chl) and phenology (study of the phases of the phytoplankton seasonal) are key to understanding many aspects of marine community structure and function. In new work, CBIOMES investigator Marie-Fanny Racault used remotely sensed ocean-color data to study patterns of variability and trends in phytoplankton Chl and phenology within the Mediterranean Sea. Continue reading “Trends in Mediterranean Phytoplankton Phenology from Ocean-Color”
A simple finite difference‐based approximation for biogeochemical tangent linear and adjoint models
by Helen Hill for CBIOMES
CBIOMES investigators Paul Mattern and Chris Edwards present a technique that accurately approximates tangent linear and adjoint models for data assimilation applications based only on evaluations of the nonlinear model. The resulting approximation offers a simple way to create readily maintained tangent linear and adjoint model code as only major changes to the nonlinear model formulation necessitate modifications of the tangent linear or adjoint model code. Continue reading “A simple finite difference‐based approximation for biogeochemical tangent linear and adjoint models”
Using MEP to Describe Microbial Biogeochemistry over Time and Space in a Meromictic Pond
by Helen Hill for CBIOMES
CBIOMES investigator Joe Vallino leverages the principle of maximum entropy production (MEP) to understand microbial biogeochemistry in a Falmouth, MA pond. Continue reading “Using MEP to Describe Microbial Biogeochemistry over Time and Space in a Meromictic Pond”
Phytoplankton Realized Niches Track Changing Oceanic Conditions at a Long-Term Coastal Station off Sydney Australia
by Helen Hill for CBIOMES
CBIOMES researchers in the Dalhousie Group looking at changes in phytoplankton biogeography in response to changing climate find mean phytoplankton niches closely tracked changes in mean temperature, while the mean salinity and mixed layer depth realized niches were consistently at the extreme range of available conditions at a study site near Sydney Australia. Continue reading “Phytoplankton Realized Niches Track Changing Oceanic Conditions at a Long-Term Coastal Station off Sydney Australia”
