1. Updates from last meeting
Report by executive officer Taka Hirata:
The new MAREMIP website hosted at Hokkaido University is now up and running and can be viewed from:
A password-protected area has been developed where the MAREMIP team can share technical information,
lists of on-going projects and paper drafts.
2. Steering committee update
The current MAREMIP steering committee consists of the following team members:
Scott Doney (Chair) (firstname.lastname@example.org)
John Dunne (email@example.com)
Laurent Bopp (firstname.lastname@example.org)
Takafumi Hirata (email@example.com)
Taketo Hashioka (firstname.lastname@example.org)
Meike Vogt (email@example.com)
Recent changes of committee members:
Yasuhiro Yamanaka (resigned from position of co-chair)

3. Data management
Pankai Kumar Sinha, a post-doc at Hokkaido University was appointed to quality control all MAREMIP data.
Pankai also applied a common land mask with identical fill values to all data sets.
Multiple data hosts:
All MAREMIP data currently hosted at Hokkaido University is to be co-hosted at IPSL alongside OCMIP/CMIP5 data
(arranged in collaboration with Laurent Bopp). A transfer of the data to IPSL (in collaboration with Laurent Bopp)
is planned once the quality control of the data has been completed (April 2014).
4. Update from collaborations with other MIPs
4.1 Clarification of link between MAREMIP and CMIP5:
View of SSC:
Coupled carbon-climate Earth System Models including ocean ecosystem models are being increasingly utilized
to study ecosystem interactions at the global scale particularly in the context of climate change,
and were recently highlighted as a novel and important contribution to the Fifth Coupled Model
Inter-comparison Project (CMIP5) in support of the Fifth Assessment of the Intergovernmental Panel
on Climate Change. As CMIP is centrally focused on the application of marine ecosystem models
to physical climate through carbon cycling, it does not necessarily prioritize state of the art
marine ecological representation, whose developments range in focus from basic biological
understanding to specific living marine resource applications.
The MARine Ecosystem Model Inter-comparison Project (MAREMIP) spans this gap,
recognizing the ongoing importance of dynamic ocean-only and offline ocean configurations serving
at the frontiers of ecosystem model development. As such, MAREMIP seeks to as broadly as possible engage
the global marine ecosystem modeling community through a focus on the implications of physiological,
ecological and biogeochemical representations rather than physical circulation differences between models
(such as the focus of the CMIP and Ocean Carbon Model Inter-comparison Project, or OCMIP),
and provide the biogeochemical and ecological linkages in support of more applied efforts (i.e. FISHMIP).
4.2 Collaborations with other MIPs:
FISH-MIP - Collaboration through the exchange of MAREMIP model output:
MAREMIP primary production, O2, SST and carbonate system data to be used as
input for future projections of fish stock dynamics.
Ocean Color Climate Change Initiative (OCCCI)− Collaboration through the exchange of validation data:
OCCCI would like to offer their satellite data products for any satellite time period suitable for our project
(needs to be defined in collaboration with OCCCI). Meeting/workshop of OCCCI participants after the AMEMR conference
in June, 2014 in Plymouth, UK.
5. Update from MAREDAT
MAREDAT Special Issue
published in the journal Earth System Science Data in final form in July, 2013 with 11 papers.
published in many international news outlets (July, 2013).
for the continuation of MAREDAT (MAREDAT2015) submitted in 2013,
but not funded. Erik Buitenhuis (UEA) is trying to rewrite the proposal so it is in better shape
for resubmission to SCOR.
Next data collection phase planned for winter 2015/2016, but this will depend, in part,
on get funding for the second round.
Current plan for 2014 - 2015 is the exploration of the existing MAREDAT database
and publication of the first set of analysis papers (MAREMIP Phase 1).
6. Scientific contributions to the Hawaii MAREMIP meeting
Cecile Rousseaux (group Watson Gregg):
Comparison of PFT-/group-specific PP in models and satellite algorithms,
and correlation with environmental variables.
Maria Kavanaugh (group Scott Doney):
Dynamic classification of ocean surface into seascapes with common (bio)physical properties.
Intends to perform analysis on MAREMIP hindcast results and identify drivers of seascape dynamics.
Charlotte Laufkoetter (group Meike Vogt/Niki Gruber):
Project 1: Trends in primary production and their drivers between 2012 and 2100 −
where do MAREMIP models differ and why? (to be submitted during the next few months)
Project 2: Pathways of and carbon fluxes through the food-web in the different MAREMIP models
− from PP to export
Project 1: changes in phytoplankton composition in the different MAREMIP models between
2012 and 2100.
Project 2: Update of Longhurst provinces from a biogeochemical perspective -
differences between MAREMIP models.
Project 3: Changes in phytoplankton phenology between 2012 and 2100 in the MAREMIP model suite.
Beyond zooplankton as a black box: Present and future food web dynamics in different MAREMIP models.
Meike Vogt (with MSc student Julia Brandenberg):
Drivers of changes in phytoplankton dominance patterns in different MAREMIP models for 2012 - 2100.
7. MAREMIP Papers and co-authorship policy
Set of core papers:
Scott Doney to write overview paper for MAREMIP phase 1 (spring 2014):
All groups that participate to add as many co-authors as desired to the introductory paper.
Paper to include a description of simulations and models, and scientific content of the paper
to be determined in collaboration with SSC members and key MAREMIP analysts.
Other non-core publications:
Set of core papers to be determined in agreement with SSC:
These should be co-authored by all main developers of the participating models.
Currently planned core publications:
- Laufkoetter et al. 2014a,b (PP, export);
- Hashioka et al. 2014a,b,c (to be discussed with first authors papers);
- Sailley et al. 2014;
- Brandenberg and Vogt et al. 2014
- Kavanaugh et al. (seascapes; hopefully submitted in 2014)
- Rousseaux et al. (PFT specific PP)
Permission for free data use with the SSC to publish a recommendation
on MAREMIP website for data use policy:
-need further input from MAREMIP community on need for possible initial data protection period
(1-2 years from submission? Until publication of core MAREMIP papers?)
- "All data users to contact data originators about the intended use of
model results ahead of time, and to offer co-authorship to data contributors,
as a courtesy, if they contribute substantively to the analysis and writing. If authorship is not required by data contributor, first authors of papers resulting from MAREMIP data should at least acknowledge all data contributors in the respective section of the resulting paper and cite the relevant MAREMIP Introduction and/or core papers."
8. Moving forward
- MAREDAT proposal to be resubmitted to SCOR in 2014.
- MAREMIP funding - to be determined.
- Marcello: European groups will be submitting a proposal for the continuation of OCMIP to the next
round of European funding (Horizons 2020). Due to its focus on biological issues, this proposal has
potential for overlap with the scientific aims of MAREMIP phase 1.
MAREMIP to clarify its position relative to OCMIP.
Potential for collaboration? Marcello to take this up with Jim Orr, MAREMIP SSC to follow up on this.
- Clearly, for MAREMIP phase 1 to be successful in the future,
funding is needed for its continuation. However, the issue of common funding is still unresolved.
- MAREMIP should consider including the community of trait-based modellers in the next phase (phase 2),
in order to address further biological questions that require a higher biological complexity.
One opportunity will present itself during the IMBER meeting in Bergen in June, 2014,
where Scott and Meike will co-chair a modelling session with Φyvind Fiksen, Mick Follows and Thomas Kiφrboe.
One future priority should be the development of models with flexible stoichiometry.
These could be developed jointly and/or evaluated within MAREMIP.
