Ground Control Points along the coastal plain of Babitonga Bay-Santa Catarina-Brazil
No full textGround Control Points (topography) obtained along the coastal plain of Babitonga Bay- Santa Catarina, Brazil. Fieldwork was conducted in August 2017 to collect planialtimetric data using a Trimble Catalyst antenna equipped with a Differential Global Navigation Satellite System (GNSS) with a sub-meter correction. The planimetric data (±30 cm) and altimetric data (±10 cm) for the GCPs were obtained using the Catalyst and theodolite, respectively. Coordinates of Ground Control Points were obtained by drone aerophotogrammetry using the Agisoft Metashape Professional version 1.8.4
Estimated ages of sediment core SF-09 obtained along the coastal plain of Babitonga Bay-Santa Catarina-Brazil
No full textThe cores were collected during the winter season in August 2017 using Russian-type sampling equipment. Sediment cores were obtained from tidal flats colonized by mangroves (SF-07, SF-08), herbs (SF-09), and ombrophilous forest (SF-10)
Results of direct shear experiments on intact and powdered samples from the submarine flank of Kilauea volcano (Hawaii, USA): Experiment descriptions
No full textWe performed laboratory friction experiments on simulated fault gouges and intact samples from the submarine flank of Kilauea volcano (Hawaii, USA) and measured the velocity-dependence of friction in velocity-step tests. Moreover, we have directly measured cohesion on the fault gouge and intact samples from Kilauea's submarine flank. The experiments were carried out using a single-direct shear device at room temperature. For the shearing tests, the samples simulating fault gouge were crushed and sieved to a grain size of < 125 µm. The intact samples were tested as mini-cores. All experiments were carried out under fluid-saturated conditions (3.5 % NaCl brine) and under an effective normal load of 10 MPa
