	abstract = {Coastal  morphologic  features  associated with  past  shoreline  transgressions  and  sea-level  highstands  can  provide  insight  into  the  rates  and  processes  associated  with  coastal  response  to  the  modern  global  rise  in  sea  level.  Along  the  eastern  and  southern  Brazilian  coasts  of  South  America,  6000  years  of   sea-level   fall   have   preserved   late-stage   transgressive and sea-level highstand features 1{\textendash}4 m above present mean sea level and several  kilome  ters  landward  of  modern  shore-lines.  GPS  with  real-time  kinematics  data,  ground-penetrating  radar,  stratigraphy,  and  radiocarbon  dating  within  a  2{\textendash}3-km-wide  river-associated  strandplain  in  central  Santa  Catarina  (southern  Brazil)  uncovered  a  diverse set of late-stage transgressive and high-
stand  deposits.  Here,  the  highstand  took  the  forms of (1) an exposed bedrock coast in areas of high wave energy and low sediment supply; (2)  a  3.8-m-high  transgressive  barrier  ridge  where  landward  barrier  migration  was  prohibited  by  the  presence  of  shallow  bedrock;  and  (3)  a  complete  barrier-island  complex  containing a 5.2-m-high barrier ridge, washover deposits, a paleo-inlet, and a backbarrier lowland, formed in a protected cove with ample sediment supply from small local streams and the erosion of upland sediments. Similar signatures of the mid-Holocene highstand can be  traced  across  all  coastal  Brazilian  states.  This  study  presents  the  first  complete  compilation of the diversity of these sedimentary sequences. They are broadly classified here as exposed bedrock coasts (type A), back barrier deposits  (type  B),  transgressive  barrier  ridges (type C), and barrier-island complexes (type D),  according  to  localized  conditions  of  upland  migration  potential,  wave  exposure,  and  sediment  supply.  These  Brazilian  
systems  present  a  paradigm  for  understanding future coastal response to climate change and accelerated sea-level rise: the recognition of a minimum threshold sea-level-rise rate of ~2  mm  yr{\textendash}1 above  which  transgression  proceeded too rapidly for the formation of these stable  accretionary  shoreline  features  demonstrates the nonlinearity of coastal response to sea-level change, and the site specificity of conditions  associated  with  the  formation  of  each  highstand  deposit  type,  even  within  a  single  small  embayment,  demonstrates  the  non-uniformity of that response.},

	abstract = {Recent bathymetric, backscatter, and seafloor sediment samples demonstrate that a large sand sheet was formed in the inner shelf by the reworking of the Merrimack River lowstand delta (deposited 12 kya; currently at 45 m depth) and braid plain during the Holocene transgression. Asymmetric bedforms and distinct grain size distributions suggest the sand sheet is actively being reworked by inner-shelf processes.Bottom sediments range from silty sand at the submerged delta to coarse sand and fine gravel in the innermost shelf (depth: 10-50 m). Coarse-grained sand comprises an expansive (32 km(2)) featureless sand sheet centered off the Merrimack River. Fine-grained sand discontinuously overlies this sand sheet in many locations and forms long wavelength (100 - 800 m), low amplitude (1-2 m), asymmetrical bedforms. Sets of these bedforms are oriented from slightly oblique offshore to onshore; several bedform sets are located within I km and oriented orthogonally to one another. Along the paleo-delta front north-northwest oriented bedforms are dominant. Inshore of these features, the bedforms become more closely spaced and have orientations to the west and west-southwest. Preliminary data suggest that the combined forces of instantaneous storm-wave generated shear stress and storm-induced currents associated with high energy northeast storm events may be responsible for sand sheet reworking and bedform development.
