title: NOAA/WDS Paleoclimatology - Fraser River Basin 450 Year Seasonal Streamflow Reconstructions

description: The recent intensification of floods and droughts in the Fraser River Basin (FRB) of British Columbia has had profound cultural, ecological, and economic impacts that are expected to be exacerbated further by anthropogenic climate change. In part due to short instrumental runoff records, the long-term stationarity of hydroclimatic extremes in this major North American watershed remains poorly understood, highlighting the need to use high-resolution paleoenvironmental proxies to inform on past streamflow. Here we use a network of tree-ring proxy records to develop 11 subbasin-scale, complementary flood- and drought-season reconstructions, the first of their kind. The reconstructions explicitly target management-relevant flood and drought seasons within each basin, and are examined in tandem to provide an expanded assessment of extreme events across the FRB with immediate implications for water management. We find that past high flood-season flows have been of greater magnitude and occurred in more consecutive years than during the observational record alone. Early 20th century low flows in the drought season were especially severe in both duration and magnitude in some subbasins relative to recent dry periods. Our Fraser subbasin-scale reconstructions provide long-term benchmarks for the natural flood and drought variability prior to anthropogenic forcing. These reconstructions demonstrate that the instrumental streamflow records upon which current management is based likely underestimate the full natural magnitude, duration, and frequency of extreme seasonal flows in the FRB, as well as the potential severity of future anthropogenically forced events.

title: NOAA/WDS Paleoclimatology - Villanueva-Diaz - Santa Teresa - PIOO - ITRDB MEX119

description: Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major vegetation productivity component: woody biomass growth. Here we compile a pantropical tree-ring network to show that annual woody biomass growth increases primarily with dry-season precipitation and decreases with dry-season maximum temperature. The strength of these dry-season climate responses varies among sites, as reflected in four robust and distinct climate response groups of tropical tree growth derived from clustering. Using cluster and regression analyses, we find that dry-season climate responses are amplified in regions that are drier, hotter and more climatically variable. These amplification patterns suggest that projected global warming will probably aggravate drought-induced declines in annual tropical vegetation productivity. Our study reveals a previously underappreciated role of dry-season climate variability in driving the dynamics of tropical vegetation productivity and consequently in influencing the land carbon sink.

title: NOAA/WDS Paleoclimatology - Nanwan and Son Tra Island Coral Ba/Ca, d138/134Ba and d137/134Ba Data from 1978 to 2004 CE

description: Soil erosion in East and Southeast Asia is believed to have increased significantly since the regional economic boom of the 1970s–1980s. However, records of soil erosion are limited, making it difficult to understand and indeed verify such changes. Here we present two new monthly resolved Ba/Ca records from Porites coral skeletons from southern Taiwan and central Vietnam, supplemented with some sporadic monthly and annually resolved coral d138/134Ba data. Our records span the 1980s to the 2000s and suggest that there were intervals of elevated seawater Ba concentrations (Basw) during the intervals 1987–1995 in southern Taiwan and 1992–2001 in central Vietnam. In combination with evidence for insignificant changes in regional seawater d138/134Ba values, model simulations, and other published coral Ba/Ca records from Lanyu (offshore southeast Taiwan) and Hainan, we infer that the intervals of high Basw values are linked to soil erosion associated with land-use changes and socio-economic developments. The increased sediment loads are also likely responsible for the recent degradation of regional coral reefs. Our study provides new insights into regional soil erosion histories, which may prove useful for guiding soil conservation and sustainable land management.

title: NOAA/WDS Paleoclimatology - Lake Turkana and Victoria, Polycyclic Aromatic Hydrocarbon (PAH) Data over the Past 20 ka

description: Fire is a key ecosystem process in tropical and subtropical savannas, with a varying role that depends on hydroclimate but also on feedbacks between fire and vegetation. In savannas, fire response to changes in rainfall depends on mean annual rainfall: in arid and semi-arid systems, burned area increases as rainfall increases fuel amount, whereas in mesic systems with high fuel moisture, burned area decreases as rainfall increases. The non-linear relationship between burned area and rainfall may be due in part to changes in the constraints on fire activity that shift the limiting factor for burning in savannas from fuel amount to fuel moisture with increasing rainfall and decreasing seasonality. Vegetation-fire feedbacks can also promote a shift from fire-prone savanna vegetation to forest taxa that suppress fire as rainfall increases. However, modern observations are, by definition, constrained to short-term dynamics, and the longer-term effects of precipitation changes on fire activity have not been evaluated. These longer-term impacts are especially relevant for evaluating biome transitions changing in response to variable hydroclimate and fire activity. The Late Pleistocene and early Holocene African Humid Period (AHP; ~14.5-5.5 ka), when rainfall increased substantially across northern and equatorial Africa, provides an opportunity to examine long-term fire responses to increased precipitation at sites with different mean annual rainfall amounts. Here, we combine new polycyclic aromatic hydrocarbons (PAHs) records of paleofire activity at two East African lake basins (Lakes Victoria and Turkana) with previously published fire records (i.e., charcoal, levoglucosan) at five sites (GeoB7920-2, GeoB9508-5, Lakes Chala, Tanganyika and Bosumtwe) to examine responses of fire activity along a rainfall gradient (from <200 mm to 1500 mm). Our synthesis reveals fire dynamics that are consistent with modern ecosystem dynamics and shows that fire activity at each site followed predicted patterns across the AHP depending on initial mean rainfall, with increased fire activity at arid to semi-arid sites and decreased fire activity at mesic-to-humid sites. Results illustrate that fire responses to hydroclimate are nonlinear, such that the same direction of change in precipitation can elicit different fire responses depending on the total precipitation at a site. Accounting for heterogeneity in hydroclimate, even within biomes, may improve predictions of how fire activity will respond to future changes in rainfall regimes.

title: NOAA/WDS Paleoclimatology - Farris fire data from Mica Mountain - IMPD US03_15B

description: Fire scars are used widely to reconstruct historical fire regime parameters in forests around the world. Because fire scars provide incomplete records of past fire occurrence at discrete points in space, inferences must be made to reconstruct fire frequency and extent across landscapes using spatial networks of fire-scar samples. Assessing the relative accuracy of fire-scar fire history reconstructions has been hampered due to a lack of empirical comparisons with independent fire history data sources. We carried out such a comparison in a 2780-ha ponderosa pine forest on Mica Mountain in southern Arizona (USA) for the time period 1937–2000. Using documentary records of fire perimeter maps and ignition locations, we compared reconstructions of key spatial and temporal fire regime parameters developed from documentary fire maps and independently collected fire-scar data (n = 60 plots). We found that fire-scar data provided spatially representative and complete inventories of all major fire years (>100 ha) in the study area but failed to detect most small fires. There was a strong linear relationship between the percentage of samples recording fire scars in a given year (i.e., fire-scar synchrony) and total area burned for that year (y = 0.0003x + 0.0087, r2 = 0.96). There was also strong spatial coherence between cumulative fire frequency maps interpolated from fire-scar data and ground-mapped fire perimeters. Widely reported fire frequency summary statistics varied little between fire history data sets: fire-scar natural fire rotations (NFR) differed by <3 yr from documentary records (29.6 yr); mean fire return intervals (MFI) for large-fire years (i.e., ≥25% of study area burned) were identical between data sets (25.5 yr); fire-scar MFIs for all fire years differed by 1.2 yr from documentary records. The known seasonal timing of past fires based on documentary records was furthermore reconstructed accurately by observing intra-annual ring position of fire scars and using knowledge of tree-ring growth phenology in the Southwest. Our results demonstrate clearly that representative landscape-scale fire histories can be reconstructed accurately from spatially distributed fire-scar samples.
