Elev

This tab is used to summarize depth and elevation information. Only populate this tab if the collector provides this information–do not extrapolate depths or elevations from coordinates.

This tab includes two sets of fields for depth. The depth fields describe the depth in the water column at which a specimen was collected. The bottom depth fields describe to the depth of the sea floor. Geological specimens in the Mineral Sciences collections always come from the sea floor. To avoid redundancy, only the Bottom Depth columns are populated.

DataKind	dkAtom	dkAtom	dkAtom	dkAtom
DataType	Float	Float	Float	Text
LookupName				Elevation Modifier

The depth of the seafloor at which a collection event began

Usage

Omit for terrestrial samples and aquatic samples where the collection depth is not known.

Format

For dredges and trawls, Depth From is the depth at the point where the collecting event started. In earlier databases, this was referred to as “on bottom”.

Each of the columns in this group represents a specific unit: meters, feet, and fathoms. When adding bottom depth, you only need to fill out one of the three columns. The other two will be calculated automatically by EMu. Original values display as black and calculated values as red in the client.

If only one depth is provided, use that depth in both Depth From and Depth To. Always provide the verbatim depth, including units, in Text Bottom Depth.

The modifier field is used to indicate uncertainty in depth measurements. Use “approx.” to indicate uncertainty. The exact uncertainty can be expressed in Text Bottom Depth.

The depth of the seafloor at which a collection event ended

Usage

Omit for terrestrial samples and aquatic samples where the collection depth is not known.

Format

For dredges and trawls, Depth To is the depth at the point where the collecting event ends. In earlier databases, this was referred to as “off bottom”.

Each of the columns in this group represents a specific unit: meters, feet, and fathoms. When adding bottom depth, you only need to fill out one of the three columns. The other two will be calculated automatically by EMu. Original values display as black and calculated values as red in the client.

If only one depth is provided, use that depth in both Depth From and Depth To. Always provide the verbatim depth, including units, in Text Bottom Depth.

The modifier field is used to indicate uncertainty in depth measurements. Use “approx.” to indicate uncertainty. The exact uncertainty can be expressed in Text Bottom Depth.
