Temporal variations of water pCO2 and the air–water CO2 flux at a coastal location in the southern California Current System: diurnal to interannual scales

The aim of this work was to identify processes that cause surface CO2 partial pressure (pCO2W) and air–water CO2 flux (FCO2) variations at a coastal location in the California Current System, from semidiurnal to interannual time scales. Such processes may include sea breeze, upwelling, El Niño/South...

description The aim of this work was to identify processes that cause surface CO2 partial pressure (pCO2W) and air–water CO2 flux (FCO2) variations at a coastal location in the California Current System, from semidiurnal to interannual time scales. Such processes may include sea breeze, upwelling, El Niño/Southern Oscillation (ENSO) cycle, and “The Blob” (strong positive temperature anomalies in the NE Pacific). Sea surface  temperature  (SST,  2008–2014)  and  pCO2W  (2008–2015)  time  series  were  generated  with  data  collected from  a  MAPCO2  buoy anchored at 100 m depth and 5 km from Punta Banda (31.6ºN, 116.6ºW), Baja California, México. There were significant changes in SST, pCO2W, and FCO2 that lasted periods that were as short as a few hours and as large as interannual time frames. Spectral analysis showed significant semidiurnal, diurnal, ~15-d, and ~28-d components of variation. Time series were divided into periods according to the Multivariate ENSO Index and the Blob event. Bayesian t tests show that both pCO2W and FCO2 had high credibility of being different between periods. During La Niña conditions (2010–2011), maximum pCO2W and FCO2 values were higher, and the minimum values were lower, than during “normal,” El Niño, and Blob conditions. The pCO2W range during this La Niña event was from 131 to 864 µatm, and the FCO2 range was from–6.9 to 40.4 mmol C·m–2·d–1. The FCO2 range during the Blob was from near equilibrium to ~2.5 mmol C·m–2·d–1. The extreme values for the FCO2 integral (± standard error), for all periods, were –57.0 ± 0.01 mmol C·m–2 for El Niño, and 257.0 ± 0.03 mmol C·m–2 for La Niña. Themean FCO2 value (± standard error) was 0.04 ± 0.02 mol C·m–2·yr–1. The buoy location was found to be a very weak source of CO2 during thestudy period.

Tales procesos pueden incluir brisas marinas, surgencias, ciclos El Niño/Oscilación del Sur (ENOS) y el “Blob” (grandes anomalías positivas de temperatura en el Pacífico nororiental). Se generaron series de tiempo de temperatura superficial del mar (TSM, 2008–2014) y pCO2W (2008–2015) con datos recuperados de una boya MAPCO2 anclada a 100 m de profundidad y a 5 km de punta Banda (31.6ºN, 116.6ºW), Baja California, México. Se observaron cambios significativos en TSM, pCO2W y FCO2 que duraron periodos tan cortos como de horas y tan largos como de segmentos interanuales. El análisis espectral mostró componentes de variación significativos semidiurnos, diurnos, de ~15 d y de~28 d. Las series de tiempo fueron divididas en periodos de acuerdo con el Índice Multivariado del ENOS y el Blob. Los resultados de la prueba t bayesiana mostraron que tanto pCO2W como FCO2 tienen alta credibilidad de ser diferentes entre periodos. En 2010–2011, bajo condiciones La Niña, los máximos de pCO2W y FCO2 fueron mayores, y los mínimos menores, que durante condiciones “normales”, El Niño y el Blob, con un rango de 131 a 864 μatm para pCO2W y de –6.9 a 40.4 mmol C·m–2·d–1 para FCO2. El rango para FCO2 durante el Blob fue de cerca del equilibrio a ~2.5 mmol C·m–2·d–1. Los extremos de la integral de FCO2 (± error estándar), para periodos completos, fueron –57.0 ± 0.01 mmol C·m–2 para El Niño y 257.0 ± 0.03 mmol C·m–2 para La Niña. La media de FCO2 fue 0.04 ±0.02 mol C·m–2·año–1. La localidad de la boya fue una fuente muy débil de CO2 durante el periodo de estudio.Iniversidad Autónoma de Baja California2017-09-292021-06-03T03:55:33Z2021-06-03T03:55:33Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed ArticleArtículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/270710.7773/cm.v43i3.2707 https://hdl.handle.net/20.500.12930/7516Ciencias Marinas; Vol. 43 No. 3 (2017); 137-156Ciencias Marinas; Vol. 43 Núm. 3 (2017); 137-1562395-90530185-3880reponame:Repositorio Institucional de la UABCSinstname:Universidad Autónoma de Baja California Surinstacron:UABCSenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2707/1929Copyright (c) 2017 Ciencias Marinasinfo:eu-repo/semantics/openAccessoai:repositorioinstitucional.uabc.mx:20.500.12930/75162024-09-18T21:38:21Z
