Gravity field and steady-state Ocean Circulation Explorer - GOCE will be launched in a few weeks (10 September 2008).

Canada: Height Modernization 2009/2010

Height Reference System Modernization

Natural Resources Canada has decided to improve their height reference system. This is the basis for both mapping and many other societal areas including climate change monitoring and science.

Looks like we have ice on Mars

I've seen the pictures from Mars. Clearly indicating that something is disappearing from the crate left after a second scoop by Phoenix. I don't wish to be a party pooper, but could it also have been the wind that removed the lumps in the crate?

It is however fantastic if it really is ice. And it might well be just that.

Phoenix Mars Lander and geodesy

Phoenix Mars Lander as well as knowledge about Mars itself depend on geodesy, in particular planetary geodesy. I will put together a piece on that shortly...

Introduction To Geodesy

Earth Science

Geodesy is the science of determining the geometry, gravity field, and rotation of the Earth and their evolution in time. Traditionally, geodesy has been serving other sciences and has had many societal applications, including mapping.

With the advent of satellite, geodesy itself developed into a science, making unique contributions to the study of the Earth system, its inherit dynamics, and its response to climate change, as well as a tool underpinning a wide variety of other remote sensing techniques. Facilitated by Global Navigation Satellite Systems such as GPS, a wide and growing set of applications associated with positioning and navigation is opening up.

Geodesy is the science of determining the earth's geometry, kinematics, gravity

Internships

We do offer unpaid internships in programming and science journalism to college students or recent graduates seeking to build up their portfolios.

Development interns will need to be proficient in PHP and CSS and provide samples of work done in a multi-user environment platform and sign a non-disclosure agreement.

Science journalists will need to provide samples from a university newspaper or professional publication and list which semester they want to work.

Please use the contact info available in the footer of the page.
