CNRS-14_Merino ICB
The PI is responsible to closely follow the progress of the action, and especially to contact NEMO project manager if the delay on preview (or review) are longer than the 2 weeks expected.
Help
The action has to be detailed briefly in the 'Summary' section for later inclusion in other pages.
Edit the 'Summary' section as with an ordinary wiki page.
- Italic formatting shows the default values or help.
- Set specific TracLinks (development ticket and branch).
Out of this, the rest of the page can be edited on-line inside the form fields considering the following color code given hereafter.

Record your modifications for the section you have edited by clicking on the corresponding button at the end of the section with 'Save ...' button. Just above, the log record will be updated.
The informations inside the form fields and this wiki page itself are stored in 2 separate databases.
As a consequence, there is absolutely no risk to make any modification in the page itself as long as you don't rename the page or modify the source code of {{{#!TracForm ... }}} processors.

Digest | Improve NEMO-ICM (icebergs) ocean column properties. Proposed modifications consists in considering the ocean column properties in the dynamics and thermodynamics parametrizations of the NEMO-ICB module: 1- In the computation of the ocean drag term for the iceberg dynamics equation we propose the use of the depth-integrated ocean velocity as described in equation 2.1 of Merino et al 2016, instead of considering the ocean surface velocity. In the situation where the submerged part of an iceberg is greater than the ocean bathymetry, the integrated velocity considers zero velocity for the part of the iceberg which is deeper than the ocean bathymetry. This parametrization has the effect of reducing the iceberg velocity when icebergs transit through shallow regions of the ocean. We have chosen not to stop or stuck icebergs in such situation since this has a strong impact in the iceberg distribution and it would require a representation of subgrid bathymetry. 2- For the computation of the basal turbulence melt rate term, we propose to consider the ocean temperature at the iceberg depth (equation 2.2 in Merino et al 2016) instead of the sea surface temperature. In cases where the submerged part of the iceberg is greater than the ocean bathymetry we propose to consider the ocean temperature at the ocean bathymetry depth. 3- For the buoyant convection term, we propose to integrate this term along the submerged part of the iceberg (equation 2.3 of Merino et al 2016), instead of only consider the ocean surface temperature. In cases where the submerged part of the iceberg is greater than the ocean bathymetry, the ocean temperature considered in the integral for the part of the iceberg which is found deeper than the ocean bathymetry (no temperature is defined deeper than the ocean bathymetry) is the temperature of the ocean at the bathymetry depth. |

Abstract
This section should be completed before starting to develop the code, in order to find agreement on the method beforehand.
Once the PI has completed this section, he should send a mail to the previewer(s) asking them to preview the work within two weeks.
Preview
Since the preview step must be completed before the PI starts the coding, the previewer(s) answers are expected to be completed within the two weeks after the PI has sent his request.
For each question, an iterative process should take place between PI and previewer(s) in order to reach a "YES" answer for each of the following questions.
Once all "YES" have been reached, the PI can start the development into his development branch.
Tests
Once the development is done, the PI should complete this section below and ask the reviewers to start their review in the lower section.
Review
A successful review is needed to schedule the merge of this development into the future NEMO release during next Merge Party (usually in November).
Once review is successful, the development must be scheduled for merge during next Merge Party Meeting.
