Dear Colleagues,

Dynamics of Atmospheres and Oceans calls for contributions to a special issue in honour
of Prof. Allan Robinson, devoted to the basic fields of investigations in marine sciences:

1) Theoretical research on physical and interdisciplinary ocean dynamics and simulations;

2) Fundamental ocean modeling and simulations including data assimilation, design of data collection experiments, adaptive sampling and real-time predictions;

3) Applied research relating to efficient multiuse and management of coastal zones, fisheries science, rapid environmental assessment and naval and maritime operations.

You can find more information on:

When submitting your manuscripts, please select "Allan Robinson Special Issue" as the article type.
Deadlines: August 2010 for submissions, Spring 2011 anticipated print of volume.

I hope you can join us in this special gift to one of the funding fathers of modern ocean
sciences,

best regards
Nadia

The 2nd Waterside Security Conference will be held in ITALY November 3-5 2010.  Abstracts are due by Monday May 31.  We are organizing sessions under the topic "Security applications of environmental modelling" with a planned session on "Operational  oceanography & security".  Please see the conference website for more details and to submit an abstract:
http://www.wss2010.org/abstracts.html

The overall goal of this conference is to bring together experts from a variety of disciplines and backgrounds who have a common interest in preventing terrorist attacks and criminal activity in ports, harbours, coastal waters, and inland waters around the world. Specifically, the conference goals are twofold:


1. While taking into account the realities of security providers, government policy, and business, *advance new maritime technologies * in:
   * Port protection
   * Counter-piracy
   * Counter-terrorism
   * Protection of critical infrastructure
   * Protection of high-profile events
   * Small boat monitoring and stopping
   * Protection of ships and energy platforms
   * Prevention of underwater intruders
   * Maritime interdiction, maritime surveillance, and information sharing

2. *Stimulate multi-disciplinary thinking* on topics such as:

   * Quantitative threat analyses
   * Communication of risk
   * Cost-benefit analyses
   * Quality and effectiveness metrics
   * Best practices
   * Table-top exercises
   * Integrated systems and their evaluation
   * Policy
   * Recommended way ahead

Dear colleagues,

We would like to bring your attention to the following session on data assimilation and inverse problems in Geosciences that will be held in Rhodes, Greece on 19-25 Sept 2010 as part of the 8th International Conference of Numerical Analysis and Applied Mathematics (ICNAAM 2010). This session will be devoted to all theoratical and practical aspects of data assimilation and inverse problems with emphasis to applications on large dimensional nonlinear problems in geosciences.
General information about ICNAAM can be found at the conference webpage

Best regards,
George Triantafyllou & Ibrahim Hoteit

Description of the topic of the session:
Data assimilation and inverse methods combine numerical models and observations to make the best possible estimates of the state and/or the parameters of a dynamical system. With the development of complex numerical models in almost every area of geosciences, these methods are increasingly becoming a necessary component to achieve more accurate predictions and reanalysis. The high complexity, nonlinearity and large dimension make the application of data assimilation and inverse methods to geophysical systems a quite challenging effort.
The aim of this mini-symposium is to gather and discuss recent theoretical and practical progress relevant to data assimilation and inverse problems in all areas of geosciences. This includes applications in atmosphere, ocean, climate, solid earth geophysics, hydrology, and petroleum engineering, etc. Contributions discussing new developments of operational
systems are also of interest. Special emphasis will be put on methods and new developments of mathematical aspects of data assimilation and inverse problems. Topics of interest include, but are not limited to:

- Data assimilation methods, e.g. 4DVAR, Kalman filtering and smoothing, nonlinear Bayesian filtering - Statistical and deterministic approaches to inverse problems
- Inverse problems with very high dimensional parameter space
- Monte Carlo methods and Bayesian computation
