Captain Cook’s Logs May Predict Future Climate Changes

04.12.2003


Pioneering worldwide research has unearthed a major new source of data for weather forecasters hoping to predict future climate changes

For the past three years a team of international experts, led by the University of Sunderland, have been examining a vast array of ships’ logs – from 1750 to 1850 – which has given one of the most accurate pictures yet of daily weather over the oceans.

These logs have never before been examined in such detail and the findings have given scientists across the globe an amazingly clear picture of weather from the past, and how it can help them to predict climate changes in the future.



Among the logs studied were those from the famous journeys of North-East-born explorer Captain Cook. However, most of the research has centred around the day-to-day accounts of regular seamen.

The University of Sunderland’s Dr Dennis Wheeler led the research team. He says: “A lot of work has been done recently with world meteorological records going back 150 years. Our work goes back much further.

"Although oceans cover 75 percent of the earth’s surface, we had very little information about the weather. These logs help us understand how climate changed in the past, which is a very useful tool when predicting climate change in the future.

“For the first time, with the exception of the Pacific, we can show the daily climate change for all major oceans between 1750 and 1850 and compare it to today’s conditions.”

Dr Wheeler worked with colleagues from a host of international organisations including the University of Madrid, the Royal Dutch Meteorological Institute, the University of East Anglia and the University of Mendoza in Argentina.

The logs are held in British, Dutch, French, and Spanish archives. The empires of these nations were large and vessels sailed regularly between major ports and cities around the world. They provided a unique and comprehensive record of daily weather conditions on a global scale.

In the 16th and 17th centuries, wind and weather were used to help navigate ships around the world’s oceans. Ships’ officers needed to maintain very accurate records of the weather and updated their logs daily and sometimes hourly. As a result, there are thousands of these records in international archives, including observations regarding wind strength and direction, and the state of the sea and sky.

Although the project is finished, the team hopes to receive funding to allow them to look at the vast amount of logbooks which have still not been examined, in a bid to further understand past climates.

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
