New Publication

Posted by | Uncategorized | No Comments

eCoast is pleased to announce the publication of a paper in the Journal of Biogeography. Co-authored by eCoast scientist Dougal Greer, in collaboration with the University of Western Australia, the publication focused on understanding the connectivity of seagrass (Posidonia australi) meadows around Victoria and southern New South Wales in Australia.

This is a significant study as it helps us to understand the propagation of seagrass which is in decline worldwide. Seagrasses is a highly important link in the food chain as they provide food, habitat, and nursery areas for numerous species which depend on the plant.

Dougal’s role in the study was to use state of the art hydrodynamic and particle modelling to determine the potential for seagrass seeds to travel between different meadows. The study involved simulating sea grass seed transport over 19 years to provide spatial probability maps of seed settlement and hence the potential for connectivity between separate sea grass meadows. Results were compared with connectivity patterns established by genetic analysis of sampled sea grass shoots from across the meadows and was found to be in good agreement.

Global Wave Conference Wrap-Up

Posted by | conference, News, Uncategorized | No Comments

From October 11-14, 2015 eCoast’s Ed Atkin joined a force of like-minded groups and individuals at the 4th Global Wave Conference (GWC) held in Cornwall in the far south west of England. The aim of the conference was to meet, discuss and share information on worldwide efforts related to surfbreak conservation and coastal environmental protection. Among the topics discussed were the latest solutions to better protect surf habitats, innovations in sustainability in the surf industry and lowering the impact of surf tourism. The event was hosted by Surfers Against Sewage (SAS), a UK based non-profit dedicated to protectiing Britain’s waves oceans and beaches.

The conference delegates were joined by pro surfers Brad Gerlach, Greg Long, Ramón Navarro and Tom Curren, all of whom were happy to share stories and listen to others. The pros were all inspirational in their own right, however the conference presentations and the people who gave them were just as impressive.

Credit must go to Surfers Against Sewage who not only organised a stunning venue and a seamless conference, they managed for the speakers and delegates to meet with members of parliament in the Churchill Room of the House of Commons, Westminster Palace, London. It was a grand finale, with an address by Steve Double, the MP for the sub-region where the conference was held and awards presented to Tom Curren, for his efforts in setting up Surfrider Foundation Europe, and Chris Hines (MBE), the co-founder of Surfer Against Sewage.

Anticipation for the next conference is high with a real sense of momentum in bringing like-minded people together and learning from their skills and experiences. While the overriding common theme for this conference was one of collaboration, the unifying force, which probably spans each of the conferences to date, is clearly the passion to protect. Hopefully this passion will be strong enough to further long-standing alliances between diverse, yet undeniably enthusiastic contributors, in to creating a unified body, a Global Wave Alliance of surfers, scientists and activists dedicated to protecting and preserving the world’s surfing resources.

 

New Zealand’s surf break protection message goes global

Posted by | conference, News | No Comments

To protect the surf breaks and coastlines around the world, science has to be in the mix.

That’s the message eCoast Marine Consulting and Research scientist Ed Atkin will be taking to the Global Wave Conference in Cornwall on the southwest coast of England next week.

The event will gather some of the world’s leading enviro-surf NGOs, researchers, oceanographers, environmentalists, activists, surfers and politicians to discuss the biggest threats to global surfing habitats and the increasing importance of protecting our oceans and surf breaks.

Coastlines worldwide are subject to ongoing development and resource extraction, and New Zealand’s coastlines are no exception. What makes New Zealand unique is its national policy safeguarding its surf breaks to ensure development is sustainable long-term.

“To have it in law that you have to consider any potential impacts regarding the access, amenity value and mechanics of our surf breaks, New Zealand is a very lucky country, but also leading the world in resource management of this kind,” says Atkin.

Atkin will be discussing the strength of the New Zealand Coastal Policy Statement and how science has been used to increase its effectiveness in a variety of scenarios across the country, including the Whangamata Bar, Aramoana, Taranaki, and surf breaks in the Greater Wellington region.

The Global Wave Conference will tackle other themes including protecting and managing natural surfing heritage, the threat of marine litter, water pollution and climate change, the importance of ‘blue health’ – human health & wellbeing, and ‘surfonomics’ – the growing impact and importance of the economic value of surfing to coastal communities.

eCoast scientists working to reduce tsunami risk in New Zealand

Efforts in tsunami hazard mitigation by eCoast Marine Consulting and Research are in-line with recommendations found in a recent report produced by the New Zealand Earthquake Commission.

Key findings from the EQC-commissioned report ‘Tsunami risk facing New Zealand’ released earlier this month include the need to complete evacuation planning, improve early warning and communication systems and provide better information for decision–makers during tsunami events.

eCoast director and senior consultant Dr Jose Borrero and his team have studied tsunamis for over 20 years and have been working on these issues both in the Waikato region and nationwide for a number of years.

Dr Borrero explains “Our efforts in the Waikato Region include computer modeling of ‘worst-case’ tsunami events for the purposes of evacuation planning. For these studies, we are assuming that a ‘Japan-sized’ earthquake occurs on the large fault line running to the east of New Zealand.”

“This is not fanciful thinking; this kind of earthquake has happened before and could very well happen here. The waves from such an earthquake would reach the Coromandel coast in less than an hour and produce substantial inundation and potential devastation throughout the region,” he adds.

However, eCoast’s studies are not limited to these extreme, yet relatively rare local events. Dr Borrero and eCoast have recently completed a multi-year research project focusing on the more commonly occurring Pacific-wide tsunamis and how they affect New Zealand’s economically vital ports.

Dr Borrero explains that currents caused by a tsunami from across the Pacific can damage or destroy a port without causing any substantial flooding. “This occurred in California after the 2011 Japan tsunami. The Port of Crescent City was destroyed, yet the waters never rose above the high tide mark,” said Dr Borrero.

“Using detailed computer models, we can identify areas within a port or harbour that are particularly vulnerable to tsunami induced currents. We can also determine when these currents will commence and how long they might last – and in most cases, because of the long travel time across the ocean, this can be done before the tsunami arrives on New Zealand shores. This provides ample time for a warning or evacuation order and minimizes the chances of a false alarm.”

Dr Borrero will be presenting some of his findings at the upcoming Coasts and Ports Conference to be held at the Pullman Hotel in Auckland from 16-18 September 2015.
