Program / Content
In the LOTRED-SA 3rd Symposium we plan to consolidate the previous community achievements, involve researchers and stimulate PAGES 2k relevant research in tropical Central and South America, and generate momentum in the emerging PAGES 2k activities for South America as considered at the PAGES OSM in Goa 2013. Therefore, in this event we will:
Review existing and new observational data sets, discuss new proxies and techniques (analytical and numerical, data analysis, calibration).
Discuss proxy-climate relationships, modern climate and paleoclimate dynamics
Examine those lessons from the Past of value for the Future
Review Human and climate impacts on ecosystems, climate-human interactions (PAGES Focus 4), and the impact of extreme climate-related events in the region: volcanoes, tsunamis, and hurricanes.
Data collection and management, community achievements
Model past climate (2k, Holocene)- Data–model comparison, data assimilation, data synthesis (reconstructions), and gear up for the Final PAGES 2k Synthesis in 2016.
Scientific Sessions
Modern climate dynamics – the Present as a key to the Past:
Instrumental and reanalysis period contributions or from climate model simulations providing insights into the interpretation of paleoclimate records, responses to forcing mechanisms, teleconnection patterns, and large-scale atmospheric phenomena are welcome.
Paleoclimatic records from continental and marine environments:
Regional reviews or new data sets from paleoclimatic archives such as lake, fluvial, and marine sediments, speleothems, tree rings, ice cores, and corals, as well as documentary sources are welcome. Though this session focuses on climate variability for the past 2 kyr, Holocene high-resolution records are also welcome. Quantitative, high-resolution approaches are of particular interest.
Modeling past climate and data–model comparison:
Contributions from long RCM or GCM simulations providing insights into regional climate responses to forced and unforced natural variability and anthropogenic forcing, teleconnections and large-scale phenomena are welcome. Comparisons between model simulations and paleoclimatic data and data assimilation studies are of special interest.
Human – climate interactions and the impact of extreme climate-related events (e.g. tsunamis, volcanoes):
Regional reviews and original research contributions dealing with human- climate interactions in Central and South America, showing how climate change or extremes may have impacted on human activities, or how humans have modified ecosystems and their functioning, which in turn might have modified regional climate modes, sea level, and so on.
Data integration and regional syntheses:
Studies integrating different data sets from across larger regions (multi-proxy and multi-site) and regional syntheses are invited in this Session.

Pre-congress Training Course
This intensive two-day course is designed for students and young scientists undertaking proxy-based and modeling-based research in palaeoecology and paleoclimate in South and Central America. It aims to provide specific training on theoretic and practical tools used on radiocarbon chronology, integration of archives, proxies and sites, in order to reconstruct past climate and environments. It will provide training on the building of age models, and the spatial interpretation of paleodata focusing on challenges and opportunities of multi-proxy analysis over time. Various software packages will be used, such as the Neotoma Paleoecology Database, the popular open-source software of R for statistical analysis and Quantum GIS for spatial analysis.
Participants: 30 people

Lectures:
Dr. Maarten Blaauw, Queen's University, Belfast, UK. Palaeoecologist with a vast experience on basic and Bayesian age-depth models and their application to a large and growing number of sites across the globe.
Dr. Alexander Correa-Metrio, Institute of Geology (UNAM), Mexico. He is an expert of Neotropical climates and terrestrial ecosystems through the Quaternary. His research includes modern and fossil records aiming to integrate them to produce quantitative environmental reconstructions.
Ms. Suzette Flantua: University of Amsterdam, Holland. She is in charge of the Latin American Pollen Data Base. She is expert in the application of Geographic Information Systems (GIS) and Remote Sensing on the spatial analysis of landscape, sustainable use of natural resources and climate change.
Field Trip
Geomorphology, neotectonics, and paleolimnology of the Santa Fé–Sopetran Basin. During this, one-day trip, we will travel along the Santa Fé–Sopetrán Basin, west of Medellín, to examine: (1) geomorphologic features and evidences of neotectonic activity along the Cauca–Romeral Fault system and, (2) discuss the paleolimnology the late Holocene San Nicolás terrace that contains a unique, high resolution, ria lake succession of laminated sediments whose hydrological/sedimentological multi-decadal frequencies were controlled by the dynamics of the intertropical convergence zone. By noon, we will enjoy lunch and spend some time at the colonial village of Santa Fe before returning to Medellin in the evening.
Participants: 20 people. Cost: U$30.- (Registration at desk until July 9). It includes bus transport, a field guide, beverages and a buffet lunch.
Leaders: Maria Isabel Velez (University of Regina, Canada), Claudia Patricia Lalinde (Integral) and José Ignacio Martínez (Universidad EAFIT).
