Welcome to the Tague Team Lab at UCSB!

The Tague EcoHydrology lab focuses on watershed research, addressing the feedbacks among terrestrial vegetation, surface hydrological processes, and atmospheric conditions. We use a variety of techniques to examine the impact of changes in climate and land use on ecosystem health and water resources.
Please scroll through our blog below to see what we’ve been up to!

All are welcome to attend our weekly lab meetings and take part in presentations and scientific discussions. See our Lab meeting schedule & events page for information on each week’s topic or presenter. Meetings are held in the Bren hall lab wing, room 1005.

New Pub: Remote sensing used to look at urban drought response

In this new publication, functionally and seasonally distinctive remote sensing variables were used to quantify changes in urban vegetation canopy conditions during droughts.

Naomi interviewed on ‘Who’s your Data?’ podcast

Naomi Tague was recently interviewed by Gilad Barash on his ‘Who’s your Data?‘ podcast about her research predicting and forecasting forest fire frequency and severity, data used in models, machine learning, and her work in developing ways to visualize the results to help officials and the public understand the processes and impacts of fire on our landscapes.

Tague presentation at AI4ESP workshop

Last week Naomi Tague presented “How Big Data and Machine Learning Can Complement Process-based Ecohydrology Models” at the Artificial Intelligence for Earth System Predictability (AI4ESP) workshop.

The AI4ESP initiative is a collaboration between DOE management and laboratories to understand the paradigm shift required to enable AI across the MODEX enterprise, in part by determining the most impactful applications along the observation-modeling continuum.

156 White Papers were solicited for the development and application of AI methods in areas relevant to EESSD research, with an emphasis on quantifying and improving Earth system predictability, particularly related to the integrative water cycle and extreme events. Submitted white papers were used to inform the design of three sequential workshops (conducted in 2021-2022) focused on answering the question:

How can DOE directly leverage artificial intelligence (AI) to engineer a substantial (paradigm-changing) improvement in Earth System Predictability?

New Publication: Impacts on water resources in a low-to-no snow future

In this review paper “A low-to-no snow future and its impacts on water resources in the western United States” in Nature Reviews Earth & Environment, author analysis of scientific studies on snow loss use a new low- to-no snow definition that suggests that in approximately 35-60 years, low-to-no-snow winters will become persistent in the western U.S. if greenhouse gas emissions continue unabated.

Carbon/Water tradeoffs & management objectives

New publication in Environmental Research used the RHESSys model to quantify the tradeoffs between carbon sequestration and water fluxes under different climate and land management scenarios in abandoned cropland areas in Mediterranean mountains.

Khorchani, M., Nadal-Romero, E., Lasanta, T., Tague, C. (2021) Carbon sequestration and water yield tradeoffs following restoration of abandoned agricultural lands in Mediterranean mountains, Environmental Research 112203. doi.org/10.1016/j.envres.2021.112203

New publication characterises spatial variation in shallow soil moisture

The goal of this study was to characterise spatial variation in shallow soil moisture at the plot scale by relating the mean of measurements collected in a plot to the standard deviation, as spatial variation of soil moisture over very small areas (<100 m2) can have nonlinear impacts on cycling and flux rates.

Scaife, C.I., Duncan, J.M., Lin, L., Tague, C., Bell, C.D., Band, L. (2021) Are spatial patterns of soil moisture at plot scales generalisable across catchments, climates, and other characteristics?

Which mechanisms control the change in water yield following a beetle outbreak?

In this new publication, RHESSys is used to explore the mechanisms that control the change in water yield following a beetle outbreak. Results indicate that the response to beetle-caused tree mortality is nonlinear – the direction of water yield change was location specific & driven by inter-annual climate variability, .
