Abstract
High-Resolution Sub-Bottom and Magnetometer Data From Southeastern Brazilian Coast
Highlights
Sub-bottom profilers are used across shallow and deep oceanic waters with several applications, such as sea-level studies (e.g., Bastos et al, 2010; Koša, 2015; Aquino da Silva et al, 2016; Yoo et al, 2016), sedimentation process (e.g., Miller et al, 2013; Alves and de Mahiques, 2019), gas seeps (e.g., Benites et al, 2015; Michel et al, 2017), geomorphology (e.g., Jobe et al, 2011; Gomes et al, 2016), and others
Marine magnetometer data have been used for most various studies, as archeological (Boyce et al, 2004), environmental (Boyce et al, 2001), engineering (Yu et al, 2007), and geological, mainly for mineral exploration (Dehler and Potter, 2002) and academic purposes (Müller et al, 1997)
Despite its importance to the oceanographic evolution of the region, it has still been poorly studied. This new dataset will contribute to future comprehension of the geologic and oceanographic evolution
Summary
Sub-bottom profilers are used across shallow and deep oceanic waters with several applications, such as sea-level studies (e.g., Bastos et al, 2010; Koša, 2015; Aquino da Silva et al, 2016; Yoo et al, 2016), sedimentation process (e.g., Miller et al, 2013; Alves and de Mahiques, 2019), gas seeps (e.g., Benites et al, 2015; Michel et al, 2017), geomorphology (e.g., Jobe et al, 2011; Gomes et al, 2016), and others. The Boqueirão Strait in the northern coast of São Paulo (Southeast Brazil) connects two semi-enclosed bays, allowing water exchange between them (Mahiques and Souza, 1999). New seismic and magnetometer data were acquired on the region of the Boqueirão Strait during a cruise between November 26 and 30, 2018, onboard R/V Veliger II from Instituto Oceanográfico of Universidade de São Paulo.
