This study investigated the distribution and origin of organic carbon (OC) and aliphatic hydrocarbons (AHs) in sand (≥ 63 μm) and mud ( 100 μg/g dw) concentration of the unresolved complex mixture and a high proportion (31%) of petrogenic n-alkan

Eutrophic estuaries receive organic matter (OM) inputs from multiple sources. This study evaluated the distribution and origin of sedimentary OM in an eutrophic estuary (Pina Sound, NE Brazil). Thirteen samples were collected in the sublittoral in ad

This letter proposes an efficient method based on the steered-response power (SRP) technique for sound source localization using microphone arrays: the refined volumetric SRP (RV-SRP). By deploying a sparser volumetric grid, the RV-SRP achieves a sig

Publikováno v: Brazilian Journal of Oceanography, Vol 62, Iss 1, Pp 65-69 (2014)

Antifouling systems (AFS) are physical or chemical treatments that control or prevent biological fouling on submerged surfaces (IMO, 2001). Tributyltin-based compounds have been used as AFS since the 1960s. These chemicals were soon recognized as ide
