Earth Observation: Past, Present and Future

Mike Tuohy, Massey University

RSNZ Manawatu Branch AGM

7.30 pm Tuesday, 18 November, Te Manawa – Art Gallery, 326 Main Street, Palmerston North

 There are thousands of satellites orbiting the Earth, some are now mere space debris, while others are used for communication, science or for more covert purposes. This presentation will provide a glimpse into the many satellites orbiting above us, with a focus on the satellites that are equipped with sensors looking down on the Earth as they orbit. These Earth observation satellites help us to monitor our environment, capturing images and providing data on the Earth’s land, oceans, coasts, and climate.

Mike Tuohy is a Senior Lecturer in Earth Science in Massey University’s Institute of Agriculture and Environment. Mike’s research expertise lies in the field of remote sensing – observing the Earth by means of the many sensors orbiting the planet on satellites. Mike is also a map enthusiast with expertise in Geographic Information Systems and image processing.

Wireless Capsule Endoscopy – Making Ends Meet

Dr David Edge, Gastroenterologist, Wakefield Capsule Endoscopy Service, Wellington

RSNZ Manawatu Branch October 2014 meeting

7.30 pm Tuesday, 21 October, Te Manawa – Art Gallery, 326 Main Street, Palmerston North

 A megavitamin sized PillCam, transmitting full colour images at 4 frames/second for 8 hours, has now enabled visualisation of the whole gastrointestinal tract. The capsule not only bridges the gap between gastroscopy and colonoscopy, but, operating in a normal physiological environment, is also able to detect small pressure-sensitive vascular lesions.

 This technology has helped unravel diagnostic problems relating to suspected gastrointestinal bleeding, iron deficiency anaemia, unexplained diarrhoea or abdominal pain, staging and monitoring Crohn’s Disease, and is also now part of the protocol for screening familial polyp syndromes. A negative study also has a major benefit in redirecting investigations away from the GI tract.

 At $3,000 per procedure, the cost issue has limited its use and delayed diagnosis while other less effective and cumulatively more expensive and time consuming techniques are performed. However, scheduling Capsule Endoscopy at an appropriate early stage in the investigation scheme, and not at the end, makes this a very cost effective and useful diagnostic tool.

Dr David Edge is a Fellow of the Royal College of Physicians and a Fellow of the Royal Australasian College of Physicians. He is a Gastroenterologist at the Wakefield Capsule Endoscopy Service in Wellington.
