2. Description of Project (Attach additional pages as necessary)
2.1 Nature and objectives of the project:
We are proposing to use the R/V Melville to conduct a multibeam survey of the slope above the
main rupture area on the thrust fault. The seafloor above the rupture area with estimated 5.5 m
of slip is 14,000 square kilometers ranging in depth from 4000 m to 400 m. Some 95% of this
area, plus the trench axis (5200 m deep) could be covered in 5 days at 12 kts, with minimal,
overlapping coverage. We will also deploy approximately 4 to 8 pressure sensors on the
seafloor which record their depth once per minute for up to one year. If the seafloor moves
abruptly again we may measure the vertical motion. This effort is time critical as subsequent
motions of the slope decrease with time following the event as well as a decrease in contrast of
newly disturbed seafloor. We will collaborate with Dr. Juan Diaz and personnel from IFM-
GEOMAR to compare our new map with a pre-existing map collect by GEOMAR before the
earthquake. We will release the data we collect with Melville immediately following the cruise
to Chilean officials and the science community.
2.2 Relevant previous or future research cruises:
Due to the nature of this request, no future cruises have been planned.
2.3 Previously published research data relating to the project:

Subject: Solicita extender permiso para buque R/V Melville
Importance: High
Estimada Karim:
He recibido un correo electrónico del Dr. David Chadwell, de la Scripps
Institution of Oceanography (Universidad de California San Diego), en el
cual me manifiesta que existe la disposición a extender el actual crucero
del buque de investigación Melville para efectuar un mapeo batimétrico de la
zona de ruptura del reciente terremoto.
El buque se encuentra operando frente a la península de Taitao. A bordo se
encuentra la colega de mi Escuela de Ciencias del mar de la PUCV, la Dra.
Ximena Contardo, quien está actuando como Observador nacional.
El plan de trabajo implica:
- el zarpe de la nave desde Valparaíso el jueves 18 de marzo a las 08:00AM;
- mapeo de la nave de la zona de ruptura (ver rectángulo en figura
adjunta) usando el ecosonda multihaz del propio buque;
- el arribo de la nave a Valparaíso el jueves 25 de marzo a las 08:00AM.
El mapeo en cuestión permitiría descubrir probables remociones en masa o
deformaciones del fondo marino que hubieran resultado, como consecuencia del
terremoto del 27 de febrero recién pasado.
El Dr. Chadwell se ha comprometido a entregar todo los datos que se obtengan
durante la campaña.
Para efectos de contactar directamente al Dr. Chadwell, por favor, remitirse
a lo siguiente:
