“…The lignin‐phenol vegetation index (LPVI), as defined by Tareq et al [2004], was calculated as: where, V, S and C are expressed in % of the sum of eight vanillyl, syringyl and cinnamyl phenols. The LPVI index has been shown to be more sensitive to changes in “freshness” of plant materials than other lignin parameters [ Tareq et al , 2004] and has been utilized in modern soils [ Otto and Simpson , 2006] and Holocene age sediments [ Yulianto et al , 2005; Tareq et al , 2006].…”

[1] Major rivers (and associated deltaic environments) provide the dominant pathway for the input of terrestrial-derived organic carbon in sediments (TOC T ) to the ocean. Natural watershed processes and land-use changes are important in dictating the amount and character of carbon being buried on continental margins. Seven core sites were occupied on the Louisiana continental margin aboard the R/V Pelican in July 2003 along two major sediment transport pathways south and west of the Mississippi River mouth. Lignin profiles in these age-dated cores ( 210 Pb geochronology) indicate artificial reservoir retention as a primary control on organic carbon quantity and quality reaching the margin post-1950, whereas pre-1950 sediments may reflect soil erosion due to land clearing and farming practices. Lignin (L 8 ) concentrations (range 0.2 to 1.7) also indicate that TOC T delivery rates/decay processes have probably remained relatively consistent from proximal to distal stations along transects. The down-core profile at the Canyon station seems to be temporally linked and connected to inner shelf deposition, suggestive of rapid cross-shelf transport. Sources of terrestrially derived organic carbon were reflective of mixed angiosperms over the last 150 years in cores west and south of the Mississippi River delta. The lignin-phenol vegetation index (LPVI) (range 130.0 to 510) proved to be a sensitive indicator of source changes in these sediments and eliminated some of the variability compared to C/V (range 0.01 to 0.4) and S/V (range 0.9 to 2.1) ratios. Stochastic events such as hurricanes and large river floods have a measurable, albeit ephemeral, effect on the shelf TOC T record. Burial of TOC T on the river-dominated Louisiana continental margin is largely driven by anthropogenic land-use alterations in the last 150 years. Land-use changes in the Mississippi River basin and river damming have likely affected carbon cycling and TOC T burial on the Louisiana continental margin over a large spatial extent as observed by similar trends in cores from across and along the margin.Citation: Sampere, T.

“…Several studies have presented coastal environmental shifts in response to Holocene sea-level changes (Behling et al, 2001(Behling et al, , 2004Blasco et al, 1996;Cohen et al, 2005aCohen et al, ,b, 2012Ellison, 2005;Engelhart et al, 2007;Fujimoto et al, 1996;Guimarães et al, 2012Guimarães et al, , 2013Horton et al, 2005;Monacci et al, 2009Monacci et al, , 2011Parkinson et al, 1994;Smith et al, 2012;Woodroffe, 1981;Yulianto et al, 2004Yulianto et al, , 2005. The effect of relative sea-level (RSL) changes is apparent in coastal environments, where significant geomorphological changes (Giannini et al, 2007) extend to the mangrove dynamics (Behling et al, 2001(Behling et al, , 2004Cohen and Lara, 2003;Cohen et al, 2004Cohen et al, , 2005aFrança et al, 2012;Guimarães et al, 2012;Lara et al, 2002;Vedel et al, 2006).…”

“…Yulianto et al . () also report that increased Fagaceae may be an indication of increased precipitation. The presence of a high‐energy fluvial system combined with the high representation of Fagaceae at Bario, however, does suggest the climate was significantly different before ∼47 000 cal a BP than it was between ∼47 000 and 30 000 cal a BP.…”

A Late Pleistocene record of climate and environmental change from the northern and southern Kelabit Highlands of Sarawak, Malaysian Borneo

A late Pleistocene vegetation record is presented, using multi-proxy analysis from three palaeochannels in the northern (Bario) and southern (Pa'Dalih) Kelabit Highlands of Sarawak, Malaysian Borneo. Before 50 000 cal a BP and until $47 700 cal a BP [marine isotope stage 3 (MIS3)], two of the sites were probably being influenced by energetic fluvial deposition, possibly associated with strong seasonality. Fluvial activity declines between 47 700 and 30 000 cal a BP (MIS3), and may be associated with a reduction in seasonality with overall stability in precipitation. The pollen record between 47 700 and 30 000 cal a BP generally shows much higher representation of upper-montane taxa compared with the Holocene, indicating often significantly reduced temperatures. After 35 000-30 000 cal a BP and until the mid-Holocene, hiatuses appear in two of the records, which could be linked to fluvial down-cutting during the late/mid Holocene. Despite the jump in ages, a pronounced representation of Ericaceae and upper-montane taxa, represented both at Bario and at Pa'Dalih, corresponds to a further lowering of temperatures during the Last Glacial Maximum (MIS2). Thick charcoal bands in the PDH 210 record also suggest periods of extreme aridity between 30 200 and 12 700 cal a BP. This is followed by energetic fluvial deposition of sands and gravels, and may reflect a significant increase in seasonality.
