Ocean dynamics is known to have a strong effect on the global climate change and on the composition of the atmosphere. In particular, it is estimated that about 70 % of the atmospheric oxygen is produced in the oceans due to the photosynthetic activity of phytoplankton. However, the rate of oxygen production depends on water temperature and hence can be affected by the global warming. In this paper, we address this issue theoretically by considering a model of a coupled plankton–oxygen dynamics… 

Global Warming Can Lead to Depletion of Oxygen by Disrupting Phytoplankton Photosynthesis: A Mathematical Modelling Approach

We consider the effect of global warming on the coupled plankton-oxygen dynamics in the ocean. The net oxygen production by phytoplankton is known to depend on the water temperature and hence can be

Fractional order oxygen-plankton system under climate change.

The results show that the effect of global warming on the oxygen production rate has been observed to be quite severe, resulting in oxygen depletion and plankton extinction.

Mathematical Modelling of Oxygen - Plankton System under the Climate Change

Oxygen production due to phytoplankton photosynthesis is an important phenomenon keeping in mind the underlying dynamics of marine ecosystems. However, despite its crucial importance, not only for

Fractional modeling of plankton-oxygen dynamics under climate change by the application of a recent numerical algorithm

This research work is dedicated to studying the dynamics of a coupled plankton-oxygen model in the framework of three non-linear differential equations. As we know that the ocean dynamics have a firm

Dynamics of Oxygen-Plankton Model with Variable Zooplankton Search Rate in Deterministic and Fluctuating Environments

It is estimated by scientists that 50–80% of the oxygen production on the planet comes from the oceans due to the photosynthetic activity of phytoplankton. Some of this production is consumed by both

Modeling and Analytical Analysis of the Effect of Atmospheric Temperature to the Planktonic Ecosystem in Oceans

In marine ecosystems, plankton is considered as the primary food producer. The growth of plankton depends on the efficiency of saturation carbon dioxide, saturation oxygen, nutrition, temperature of

Pattern Formation in a Model Oxygen-Plankton System

It is shown that close to the tipping point the spatial distribution of the dissolved oxygen tends to become more regular; arguably, this can be considered as an early warning of the approaching catastrophe.

Marine system dynamical response to a changing climate in frame of power law, exponential decay, and Mittag‐Leffler kernel

The increase of sea surface temperature in ocean changes the photosynthetic production rate of phytoplankton. Therefore, it is crucial to understand the relation between temperature and

Oxygen production due to phytoplankton photosynthesis is a crucial phenomenon underlying the dynamics of marine ecosystems. However, most of the existing literature focus on other aspects of the

Climate models predict that increasing greenhouse gases in the atmosphere will change our climate. However, the range of observations available to assess these model predictions is limited. We have

A physical-biological coupled model for algal dynamics in lakes

The biological model describes mathematically the typical properties of phyto-and zooplankton, their interactions and their response to the physical environment, which allows the study of the behaviour of Lagrangian clusters of virtual plankton that are subjected to such environments.

It is reported that the interaction of bacteria and phytoplankton is closely related to the meridional profile of water temperature, a variable directly dependent on climate.

TEMPERATURE AND PHYTOPLANKTON GROWTH IN THE SEA

The variation in growth rate with temperature of unicellular algae suggests that an equation can be written to describe the maximum expected growth rate for temperatures less than 40°C, a logical starting point for modeling phytoplankton growth and photosynthesis in the sea.

Scaling metabolism from organisms to ecosystems

A general model of ecosystem respiration based on the kinetics of metabolic reactions and the scaling of resource use by individual organisms is derived, predicting that fluxes of CO2 and energy are invariant of ecosystem biomass, but are strongly influenced by temperature, variation in cellular metabolism and rates of supply of limiting resources.

The potential for larger O2 declines in the future suggests the need for an improved observing system for tracking ocean 02 changes, and an important consequence may be an expansion in the area and volume of so-called oxygen minimum zones.

Changes in turbulent mixing shift competition for light between phytoplankton species

Competition theory is developed that predicts how changes in turbulent mixing affect competition for light between buoyant and sinking phytoplankton species, and warns that changes in the turbulence structure of natural waters, for instance driven by climate change, may induce major shifts in the species composition of phytopsized communities.
