The LOLEIF - Photo Gallery

This page will be successively actualised and supplemented with new pictures and images from public project results. 
It might be worth to visit this page from time to time ! 

The photos and images on this page as well as all other images included on the LOLEIF web site are for public attraction, information and awareness creation on the ice research.

Panel installation with tug and icebreaker
Installation of the panels to measure ice loads at Lighthouse Norstrømsgrund in the Gulf of Bothnia (Northern Baltic Sea) -
a Swedish tug boat and an icebreaker assisted in the installation work conducted by LUT personnel during summer 1999.

Panels installed at lighthouse
The installation of the panels around the basement of Lighthouse Norstrømsgrund is completed.

Lighthouse Norstrømsgrund in heavy sea
The panels had to resist high wave forces in ice free periods as well. Heavy sea state also hampered access to the lighthouse by ship and complicated the installations.

Computer room in the lighthouse
The computer room was located in the upper area of the lighthouse. During the measuring periods large amounts of real-time data loggers and computers were installed in this command post operated by Peter Jochmann of HSVA.

Camera installation at Lighthouse Norstrømsgrund
Photo and video cameras were installed on the reeling on top of the lighthouse looking down on the ice in front of the panels.

Laser scanner installed on Lighthouse Norstrømsgrund
A laser scanner was installed on the lighthouse to measure continuously the thickness of the ice during the measurement period in the year 2000.

Ice thickness profile near Lighthouse Norstrømsgrund
A series of ice drills, sampling and thickness profiles were taken by LUT within a survey on the ice in April 1999 in the vicinity of the lighthouse.

Ice force registration on Lighthouse Norstrømsgrund
Example of an ice force registration at the panels when the ice gets moving. Forces in this example with a passing ice ridge exceed 3,000 KN.

Mobilisation of equipment for full scale tests on the ice
HUT conducted a variety of ice mechanical full scale tests on the ice offshore Finland. Heavy equipment and large logistic efforts are necessary to conduct such measurements.

Ice bending test set-up by HUT
Set-up of an ice bending test conducted by HUT. A rectangular piece of ice was cut out and bent with high forces while ice mechanical parameters were measured simultaneously on the ice sample.

Ice punch test by HUT
Another ice mechanical experimental set-up from HUT was applied to punch a circular plate down through an ice ridge.

Ice sample under polarised light
From ice samples thin plates were cut and photographed under polarised light to get insight into the fine and granular structure of the ice. Fascinating images from the "artist nature" result from such investigations.

Solving questions - seaking answers !
This image shall  symbolize the large efforts and work done in the institutes by the scientists and ice modellers in the LOLEIF project elaborating the results achieved.
