Effects of dredged sediment disposal on the coastal marine macrobenthic assemblage in Southern Brazil

Abstract: The aim of this study was to evaluate the deposition impact of dredged material from Patos lagoon estuary on a benthic macroinvertebrate assemblage structure in an adjacent coastal marine area. Nine sampling stations were chosen at random in the disposal area, and nine others in the same way in an adjacent control area. Samples were collected at a 19 m depth before sediment disposal (11 July 2000), during dredging and disposal operations (25 Oct. 2000), and three months thereafter (24 Aug. 2001).

“…Port terminals are usually built in sheltered areas such as coves, bays or estuaries. Routine port activities, besides dredging activity in the navigation channels, affect the composition and distribution of marine benthic communities through removal and suspension of sedimentary material, increasing the quantity of particulate matter in the water column (ANGONESI et al 2006).…”

“…The impacts of dredged material disposal on benthic communities have been explored internationally (e.g., Jones 1986 ; Rees et al 1992 ; Harvey et al 1998 ; Valente et al 1999 ; Smith and Rule 2001 ; Stronkhorst et al 2003 ; Cruz-Motta and Collins 2004 ; Witt et al 2004 ; Angonesi et al 2006 ; Bolam et al 2006 ; Powilleit et al 2006 ; Vivan et al 2009 ; Ware et al 2010 ; Katsiaras et al 2015 ; Pezy et al 2017 ) and on the east (Leathem et al 1973 ; Diaz and Boesch 1977 ; Van Dolah et al 1984 ; Diaz 1994 ; Zimmerman et al 2003 ) and Gulf coasts (Clarke and Miller-Way 1992 ; Flemer et al 1997 ; Ray and Clarke 1999 ; Wilber et al 2007 , 2008 ) of the USA, with fewer published studies on the US west coast (McCauley et al 1977 ; Blanchard and Feder 2003 ). The majority of these studies concentrate on impacts to macro-infaunal communities (but see Pezy et al 2017 for a multi-trophic level analysis) and typically measure changes in species density and community composition including times to recovery to baseline conditions (see Wilber and Clarke 2007 for meta-analyses).…”
