Sea Level Rise

Speaker: 
Jan Even Ø. Nielsen
Seminar Date: 
24. January 2011 - 12:30 - 13:00

As part of a project coordinating meeting on Monday I will present the ongoing project 'Sea Level Rise' This talk will be open to all at NERSC.

Wave attenuation in the presence of an ice cover

Speaker: 
Timothy Williams
Seminar Date: 
20. January 2011 - 12:15 - 13:00

In this talk I will overview some of my research prior to starting at NERSC, particularly in regard to using wave attenuation to remotely sense average ice thickness.

Scale-Sensitive Coupling of Climate and Carbon Cycling and Ecosystem Production in the Southern Ocean

Speaker: 
Pedro M. Scheel Monteiro
Affiliation: 
NRE Research Fellow, Council of Scientific and Industrial Research, Stellenbosch, South Africa
Seminar Date: 
11. January 2011 - 13:15 - 14:00

The Southern Ocean Carbon - Climate Observatory is a new South African programme which aims to make a contribution to advancing the understanding of the role of the Southern Ocean in the coupled global Carbon - Climate System. This programme has a strong biogeochemical focus on carbon fluxes linked to understanding its sensitivity to large scale climatology forcing by both the SAM and ENSO. This programme combines a long term observation activity with the use of high resolution models as experimental platforms.

Physical factors influencing water quality in the Nordic Seas

Speaker: 
Anton Korosov
Seminar Date: 
17. December 2010 - 13:00 - 13:45

The report summarizes results of analysis of remote sensing, reanalysis and modeling data collected during 10 years (1998 – 2007). These data were synergistically used for studying seasonal and inter-annual dynamics of water quality in the Nordic Seas. A novel approach for merging these datasets was developed, main forcing physical factors were identified, and decadal changes of the ecosystem were estimated.

Interannual variability of sea ice export into the East Greenland Current

Speaker: 
Sara de la Rosa Höhn
Seminar Date: 
16. December 2010 - 13:30 - 14:00

A step forward in modeling the marginal ice zone

Speaker: 
Dany Dumont
Seminar Date: 
9. December 2010 - 12:15 - 13:00

I will present an overview of the progress that has been made in modeling the dynamics of the marginal ice zone during my stay at the Nansen Center. I will also discuss main research problems and challenges that need to be addressed in this field.

Clouds and the Radiation budget over the Arctic Ocean - Results from CloudSat and CALIPSO

Speaker: 
Marta Zygmuntowska, University of Hamburg
Seminar Date: 
29. November 2010 - 14:15 - 15:00

Climate Impact of Greenland Ice Sheet melting

Speaker: 
Lei Yu
Seminar Date: 
25. November 2010 - 12:15 - 13:00

The Atlantic meridional overturning circulation (AMOC) plays an active
role in global climate change. Here, three numerical simulations with
Bergen Climate model have been performed with the additional freshwater
released from the entire coast, the western and the eastern coast of the
Greenland to study the response of AMOC in the three experiments and the
potential impacts on climate. The preliminary results show the AMOC is
weakening in a similiar way irrespective of the freshwater pattern.

Sensitivity of the Arctic ocean to the Bering Strait inflow: a modeling study

Speaker: 
Borghild Ness
Seminar Date: 
11. November 2010 - 12:15 - 13:00

Water from the Pacific Ocean flowing through the Bering Strait (BS) influences the heat and salt budget of the Arctic. With salinity between 31.4 and 32.9, it contributes with approximately 50% of the fresh water input to the Beaufort Gyre reservoir. The hydrography and transport of the inflow vary significantly throughout the year. Woodgate et al. (2010) suggested that warm water intrusions may act as a trigger for the onset of the seasonal melt of ice, as in the 2007 extreme event.

The role of ocean parameters on tropical cyclones in the BOB region

Speaker: 
Lakshemi Srikomth
Seminar Date: 
7. October 2010 - 12:15 - 13:00
