Short-term spectral analysis was carried out on geochemical logging data from ODP Site 704. The FFT was used to compute the amplitude spectra of short-term overlapping segments to produce depth-period-amplitude spectrograms of the logging data. The spectrograms provided a means of evaluating the significance of the observed periodic components. The periodic components that were consistently present and prominent across a given record interval were considered to be significant. Changes in the spectrogram characteristics seem to...

Palladium, platinum, and gold were analyzed for 20 interstitial water samples from Leg 125. No Pd or Pt was detected in fluids from serpentinite muds from Conical Seamount in the Mariana forearc, indicating that low-temperature seawater-peridotite interaction does not mobilize these elements into the serpentinizing fluids to levels above 0.10 parts per billion (ppb) in solution. However, Au may be mobilized in high pH solutions. In contrast, fluids from vitric-rich clays on the flanks of...

During the cruise ARK-XXVII/3 sampling of the megafauna was conducted by the Agassiz trawl (AGT) at seven stations. Agassiz trawls were taken along transects after the photographic survey by OFOS when the ice conditions were appropriate to obtain specimens to verify taxonomic identifications based on images. Also using the retrieved AGT samples wet biomass was estimated for each transect. Trawl samples were washed through a sieve with 1 mm mesh size, sorted and preserved in...

Start location: Tamanrasset; Distance from radiation site: 10 km

Quality code: BDL - below detection limit, NQE - Analyte not quantitatively extracted from filter matrixAir volume used to calculate the below presented detection limit for each species is 1400 m**3. Where data are identified as BDL, the concentration given is 75% of the detection limit calculated using the actual air volume for each sample.

Sidescan sonar data were collected during R/V Heincke cruise HE415 with a towed multi pulse Edgetech 4200-MP. Data recording was executed along 96 parallel profiles in North Sea within German EEZ. The survey speed was 6-7 knots and the swath set to 460 m to obtain a resolution of ~1 m along track. The track distance is 400 m. In total 1,150 km² were area-wide mapped. The interpreted sediment distribution map of this data area...

Holocene paleoceanographic reconstructions along the North Iceland Shelf have employed a variety of sea surface temperature and sea ice proxies. However, these surface proxies tend to have a seasonal bias toward spring/summer and thus only provide a discrete snapshot of surface conditions during one season. Furthermore, sea surface temperature proxies can be influenced by additional confounding variables resulting in markedly different Holocene temperature reconstructions. Here, we expand Iceland's marine paleoclimate toolkit with TEX86 L: a...

Here we describe and test the addition of a clear liquid optical chamber (CLOC) to a BRUV system to improve underwater visibility when observing motile fauna in turbid waters. The CLOC method was trialled with respect to the ability of the system to identify taxa to species level in both controlled laboratory and field conditions across gradients of underwater visibility.
