Can you please send me more information on the original publisher of this software and where you have got this software from? What is the correct reference if we want to access site the software?
The NANSIS belongs to the Institute of the Marine Research, unfortunately, the page where it was supposed to be hosted is no longer working. Yes, the official website is still online, but there is nothing about the application.
You can still download the application from the following page: http://www.fao.org/in-action/eaf-nansen/topic/16074/en
This is the link to the official developer: http://www.imr.no/en
