Each polished slab was micromilled at 0.2-mm intervals along four parallel and 5-mm-wide traverses perpendicular to the lamination using a Merchantek micromill (ESI New Wave). Sample powders were analyzed using a semiautomated device (GasBench II, Thermo Fisher) linked to a Thermo Fisher Delta plus XL isotope ratio mass spectrometer.

A Merchantek MicroMill Sampling System is available for 3-D microsampling of coral and clam shell samples. This instrument uses three axis stepper motors to guide a ~50µm drill bit along a defined microsampling path, to a preset bit depth. Positioning precision is <10µm and weekly-monthly subsamples of prepared (polished, thin section) coral ...
A computerized Merchantek micromill was used to mill samples, parallel to growth banding, at increments of 0.1 mm, along radial transects from the outer edge to the centre of each section ...

The Paleoecology Lab at SU features a Merchantek (New Wave) MicroMill, a microsampling device that allows high-resolution sampling of accretionary biogenic materials for stable isotope analysis. A number of samples can be collected in sequence within a series of growth increments, e.g., in a mollusk shell or coral skeleton, that record intra ...
We have used a Merchantek MicroMill to achieve a high sampling resolution and to avoid signal smoothing from broad-interval conventional sampling, in order to capture the full isotopic variability. Stable oxygen isotopes were measured to resolve the temperature signal of the bottom water, while stable carbon and oxygen isotopes are measured to ...

New contour-following function. > Because of its high-resolution milling capability, MicroMill is extremely useful in a range of applica-tions. Two examples of these are the following: Complex crystal growth zonation: Subsampling provides high-resolution elemental isotopic chemistries, and intra-zonal variations of the crystal structure.

Merchantek EO Micromill PXC software was used to interpolate line spacing at 200 μm apart. Drilled holes were spaced 250 to 300 μm apart, as resultant pit size was 500 μm. Samples were milled to a depth between 100 and 450 μm depending on the valve. The distance from the most recent growth margin to each transected line or drilled hole was ...

Using a Merchantek Micromill, carbonate powder was drilled directly from the surface of the left valve of the shells. A 300 mm drill bit was used, which corresponds to a resolu-tion of 1–6 days depending on growth rates. To avoid surface contamination, the surface layer (50 mm depth) of each sample was re-moved, and the next 100 mm was sampled.

Corals were sectioned using a slow-speed Isomet saw, and sampled for isotopic analysis using a Merchantek micromill. Observation of sectioned corals revealed dense-less dense couplets, as in every coral studied to date from tropical to deep cold-water environments worldwide.
