Sediment Sampling
Sea Surveyor owns and operates two (2) vibratory
corers (Vibracores) capable
of collecting continuous core samples of 5, 10, 15, 20, or 30 lengths. The
sediment cores are contained within clear, 3.5 diameter, chemically inert
liners that can be cut into client-specified lengths, capped for transport,
labeled for identification, and stored on ice until delivered to the
laboratory. In addition to our
vibracores, we use a gravity corer for collecting short (1-5) cores in
unconsolidated sediments, and grab samplers for collecting surficial sediments.

The
ALPINE vibracorer is the largest
and most powerful vibratory corer ever built. This vibracore is capable of
penetrating 20, 30, or 40 into the seafloor to collect a continuous
stratigraphic sequence of soils material.
A quadropod stand allows the ALPINE vibracore to be set on the
seafloor and operate without the need to anchor the support vessel. A vessel
with 20-ton crane is typically needed to extract the core barrel from the
seafloor.

Our MINI-VIBRACORER was custom-designed for collecting 5-15 sediment cores from small, shallow-draft vessels. The Mini-Vibracore can be easily transported and assembled for short-term projects at remote sites. The Mini-Vibracore has a large, flat base that enables it to be set on the seafloor and operated without anchoring the vessel. A 1-ton crane is typically used to deploy the Mini-Vibracore.

A
GRAVITY CORER is similar to a
dart. When released from the support
vessel, the gravity corer plunges through the water and penetrates into the
unconsolidated sediments on the seafloor.
Capable of collecting 1-5 sediment cores, our gravity corer is a
quick and cheap method for sampling surficial soils.
A
PENETROMETER displays the rate of
penetration of the vibracore into the seafloor. Penetrometer data is used to determine the cores
depth-of-refusal, and can be plotted as a penetration profile to evaluate
soil consistency. |
