WP2 Ocean productivity, ecosystem structure and functioning, and C export in a changing EMS

WP2 investigates the effects of climate change and anthropogenic pressures on the EMS ecosystem and its productivity from physical, chemical, and biological perspectives – exploring the bacterial, photosynthetic, and zooplankton populations. (See description and links to student projects)

WP3 Seafloor processes and sedimentary records in a changing EMS

The EMS is an ocean region that has been dramatically affected in recent geological and historical past by natural climate change. WP3 exploits this known sensitivity to past climate change and is investigating impacts based on the recent sedimentary record, benthic environment and other relevant historical samples to elucidate changes ofkey processes and accordingly predict the response of the EMS to recent climate and environmental changes. WP3 focuses as well on the relationship between climatic and anthropogenic driven changes to altered seafloor effluxes of methane and other gases.

WP4 Biogeochemical modelling of effects of gradual changes and stochastic events on ocean ecosystems and carbon export

WP4 Leaders

Prof. Andreas Oschlies (ºÚÁÏÊÓÆµ)
Dr. Markus Pahlow ºÚÁÏÊÓÆµ
(HAIFA)

WP4 Aims

  1. Collect data from lab experiments/moorings/ships for improving plankton-ecosystem models
  2. Implement and calibrate trait dynamics to allow for adaptation of plankton ecosystems to climate change in the EMS
  3. Couple Plankton to Earth System Model to extrapolate results to other subtropical regions & global ocean

In WP4 (modeling present & future biogeochemical cycling in the eastern Mediterranean), headed by ºÚÁÏÊÓÆµ, we are using an optimality-based plankton-ecosystem model (OPPLA) to analyze the potential of plankton communities to cope with gradual climate changes and extreme events by means of adaptive changes. The model comprises optimality-based descriptions of phytoplankton physiology and zooplankton behavior. The model is implemented for off-line use and can be used in conjunction with existing physical models of the Mediterranean Sea to drive 1D and 2D simulations.

WP4 Milestones

  1. Refine temperature dependence of phytoplankton growth model based on lab observations
  2. Calibrate OPPLA with time-series and cruise data from the EMS FORE project and other sources
  3. Implement and calibrate dynamic optimal temperature in OPPLA for phytoplankton, zooplankton, and bacteria
  4. Configure OPPLA for 2D simulations to capture effects of lateral fluxes
  5. Simulate the past 50–100 years and future climate-change scenarios in the EMS
  6. Transfer the new adaptive temperature functions to the UVic Earth system model where possible
  7. Contrast climate-change scenarios with and without adaptive temperature functions

WP4 Students & Post Docs | University of Haifa

  • Hadar Berman (Post Doc) | Combining high resolution numerical modeling, satellite remote sensing and aerial photography we show that Jellyfish swarms along the Israeli coast of the EMS are structured and advected by fine scale currents
  • Yotam Fadida (PhD) | (in collaboration with from Tel Aviv University), we combine high resolution numerical modeling and satellite data to study the role of submesocale horizontal stirring in modulating the connectivity between coastal and pelagic waters of the EMS

WP4 Students | ºÚÁÏÊÓÆµ

  • David Moncayo Guzman (PhD) | We use an optimality-based plankton ecosystem model (OPPLA), largely built on first principles, to analyse plankton ecosystem behaviour in different parts of the World ocean. The generic nature of this model means that it is not specifically geared to the EMS but also that conclusions obtained with OPPLA may be more relevant for other ocean regions compared to more specialised models
