Two new reports available online

Two highly topical and relevant reports have recently been published:

The Dinard Report (Environmental Management of Deep-Sea Chemosynthetic Ecosystems: Justification of and Considerations for a Spatially-Based Approach)

"Illuminating Earth's Past, Present and Future" - IODP's science plan for the next decade of ocean drilling. 

Workshop: Ocean Mantle Dynamics: from Spreading Center to Subduction Zone

The above meeting will be held on 4-6 October 2011 at AORI, Tokyo, Japan, with an optional field trip on 2 October. Registration is now open and attendees are encouraged to post their interest as soon as possible. All details are available from the Japanese website.

In this meeting, there will be a focus on three objectives of crustal and mantle imaging, with an emphasis on mantle dynamics:

Workshop abstracts

Background and Objectives

What have and can we derive from crustal and mantle imaging beneath the ocean together with laboratory and numerical studies?

Deep Earth Sampling Report for 2010

2010 Update

WG 135 – Working Group Report 2010
1. First meeting objectives and participants
The first WG 135 Meeting took place in Woods Hole, Massachusetts, USA on 23-24 Nov. 2009. Logistical support was provided for this meeting from InterRidge, which arranged access to all meeting facilities at WHOI. The aim of this first meeting was to discuss the most relevant way to address the WG terms of reference and to clarify the expected outcomes of the WG, while discussing science plans and opportunities arising in partnership with various other initiatives.

2010 Update

Mantle Imaging WG

Chair – Nobukazu Seama (Kobe University, Japan)

In 2010, we convened a session at the EGU meeting, the title being: "Melt generation to crustal formation beneath mid-ocean ridges" and we had 12 abstracts.  However, we merged to make an oral session entitled: "Two-phase dynamics of mid-ocean ridges and other systems: theory and observation". Whilst there were not many abstracts, the session itself attracted a lot of interest.

Seafloor Mineralization Working Group Update 2010

2010 Update

As no major meeting of general interest to the deep-sea hydrothermal vent ecology and biology community was organized this year, the Vent Ecology WG has mainly been interacting at distance, through the internet.

Survey on protected hydrothermal vent sites

In response to the ISA’s request for information on hydrothermal sites of exceptional scientific value, InterRidge is seeking nominations from the scientific community for sites considered vulnerable to exploitation.

The MoHole: a Crustal Journey and Mantle Quest

The 2010 MoHole workshop in Kanazawa, Japan, followed on from several recent scientific planning meetings on ocean lithosphere drilling, in particular the Mission Moho Workshop in 2006 (Christie et al., 2006; Ildefonse et al., 2007), and the "Melting, Magma, Fluids and Life" meeting in 2009 (Teagle et al., 2009). These previous meetings eached consensus that a deep hole through a complete section of fast‐spread ocean crust is a renewed priority for the ocean lithosphere community.
