Flowline bathymetric profiles in the Atlantic and Pacific Oceans for statistical analysis

These data sets consists of approximately flowline-parallel bathymetric
profiles in the North and South Atlantic Oceans, along the northern and
southern East Pacific Rise, and along the Pacific-Antarctic Ridge. These
data are used in a paper submitted to Geophysical Research Letters
entitled "A spreading-rate dependence for periodic signals embedded
in otherwise aperiodic abyssal hills". The first zip
file, AHspectral_profiles.zip, contains unprocessed profiles,
each containing the following columns:  (1) longitude, (2)
latitude, (3) depth in m, (4) crustal age in my, and (5) half spreading
rate in 1/1000th of a cm. The second zip
file, AHspectral_processed.zip, the profiles have been processed
to be a function of crustal age, resampled at constant interval, and
detrended with an order 6 polynomial. Header gives number and data points
and sampling interval in my. The profile naming convention consists of the
cruise ID of the data collection survey (except for NEPR data, which come
from too many bathymetric sources, and so are just identified as “nepr”),
and a 3-digit code indicating (a) whether data profile was to the east
(e)or the west (w) of the ridge axis, (b) a number indicating which of one
or more profiles where utilized for that cruise ID, and then (c) a letter
indicating which segment of the profile was used. If the data were sampled
from multibeam data, that is indicated by an “mb” suffix; otherwise the
data were gathered from mgd77 trackline data files.
