Abstract. The main advancements of the Beijing Climate Center (BCC) climate system model from phase 5 Coupled Model Intercomparison Project (CMIP5) to 6 (CMIP6) are presented, in terms physical parameterizations and performance. BCC-CSM1.1 BCC-CSM1.1m two models involved CMIP5, whereas BCC-CSM2-MR, BCC-CSM2-HR, BCC-ESM1.0 three configured for CMIP6. Historical simulations 1851 2014 BCC-CSM2-MR 2005 used assessment. evaluation matrices include following: (a) energy budget at...
Abstract The paper examines terrestrial and oceanic carbon budgets from preindustrial time to present day in the version of Beijing Climate Center System Model (BCC_CSM1.1) which is a global fully coupled climate‐carbon cycle model. Atmospheric CO 2 concentration calculated prognostic equation taking into account anthropogenic emissions interactive exchanges land‐atmosphere ocean‐atmosphere. When forced by prescribed historical combustion fossil fuels land use change, BCC_CSM1.1 can...
The previous descriptions of Opisthotropis maxwelli Boulenger, 1914 and O. andersonii (Boulenger, 1888) were considered imperfect due to the limited number specimens. This may in turn cause a problem for accurate species identification. In our study, boundaries these two investigated using an integrative approach incorporating morphological characters molecular phylogenetic analyses mitochondrial Cyt b gene 26 specimens nine known collected from south-eastern China. Our results surprisingly...
Most existing propeller-driven, cruising AUVs operate with a support ship and have an endurance of about one day. However, many oceanographic processes evolve over days or weeks, requiring propeller-driven vehicles be attended by for complete observation programs. The Monterey Bay Aquarium Research Institute (MBARI) developed the 105 kg Tethys AUV to conduct science missions periods weeks even months without [1]. Here we describe three week deployment covering 1800 km at speed 1 m/s,...
Abstract An ecologically and economically disruptive harmful algal bloom (HAB) affected much of the northeast Pacific margin in 2015, during a prolonged oceanic warm anomaly. Caused by diatoms genus Pseudo‐nitzschia , this HAB produced highest particulate concentrations biotoxin domoic acid (DA) ever recorded Monterey Bay, California. Bloom inception followed strong upwelling spring transition, which introduced nutrients eliminated anomaly locally. Subsequently, moderate intermittent created...
Environmental DNA (eDNA) can be used to identify macroorganisms and describe biodiversity, thus has promise supplement biological monitoring in marine ecosystems. Despite this promise, scaling sample acquisition the size temporal scales needed for effective would require prohibitively large investments time human resources. To improve upon these problems, here we test efficacy of an autonomous eDNA sampling system compare results obtained traditional methods. The instrument consisted Sample...
Abstract. The Beijing Climate Center Earth System Model version 1 (BCC-ESM1) is the first of a fully coupled system model with interactive atmospheric chemistry and aerosols developed by Center, China Meteorological Administration. Major aerosol species (including sulfate, organic carbon, black dust, sea salt) greenhouse gases are interactively simulated whole panoply processes controlling emission, transport, gas-phase chemical reactions, secondary formation, gravitational settling, dry...
<strong class="journal-contentHeaderColor">Abstract.</strong> Changes in forest cover have a strong effect on climate through the alteration of surface biogeophysical and biogeochemical properties that affect energy, water carbon exchange with atmosphere. To quantify effects deforestation consistent setup, nine Earth system models (ESMs) carried out an idealized experiment framework Coupled Model Intercomparison Project, phase 6 (CMIP6). Starting from their pre-industrial state, linearly...
Abstract. BCC-CSM2-HR is a high-resolution version of the Beijing Climate Center (BCC) System Model (T266 in atmosphere and 1/4∘ latitude × longitude ocean). Its development on basis medium-resolution BCC-CSM2-MR (T106 1∘ ocean) which baseline for BCC participation Coupled Intercomparison Project Phase 6 (CMIP6). This study documents model, highlights major improvements representation atmospheric dynamical core physical processes. evaluated historical climate simulations from 1950 to 2014,...
Background Acute bronchitis (AB) is one of the principal causes childhood morbidity. Increasing number studies has shown that air pollution an important environmental contributor respiratory disease. However, evidence so far scarce regarding effects on AB, and it also remains unclear how risk AB will change by season age. Methods Data hospital visits for in children, meteorological factors from 1 January 2015 to 31 December 2016 were collected Hefei, China. Time-series analysis was applied...
The improvements and validation of several parameterization schemes in the second version Beijing Climate Center Atmosphere-Vegetation Interaction Model (BCC_AVIM2.0) are introduced this study. main updates include a replacement water-only lake module by common land model (CoLM-lake) with more realistic snow-ice-water-soil framework, scheme for rice paddies added vegetation module, renewed parameterizations snow cover fraction surface albedo to accommodate varied aging effect during...
A team of coordinated robots autonomously observed and sampled open-ocean microbial communities in a Lagrangian mode.
Low-frequency sound from large vessels is a major, global source of ocean noise that can interfere with acoustic communication for variety marine animals. Changes in vessel activity provide opportunities to quantify relationships between traffic levels and soundscape conditions biologically important habitats. Using continuous deep-sea (890 m) recordings acquired ∼20 km (closest point approach) offshore shipping lanes, we observed reduction low-frequency within Monterey Bay National Marine...
Abstract Environmental DNA (eDNA) is an emerging and powerful method for use in marine research, conservation, management, yet time‐ resource‐intensive protocols limit the scale of implementation. Long‐range autonomous underwater vehicles equipped with environmental sample processors (LRAUV‐ESPs) provide a new means scaling up eDNA collection processing. Here, we used metabarcoding four marker genes (mitochondrial 12S rRNA, bacterial archaeal 16S nuclear 18S mitochondrial COI), which...
The Tethys autonomous underwater vehicle (AUV) is a 110 kg designed for long-range, high- endurance operations. Performance goals include supporting payload power draw of 8 W range 1000 km at 1 m/s, and 4000 0.5 m/s. Achieving this performance requires minimizing drag maximizing propulsion efficiency. In paper, we present the design system, explore issues propeller-hull interactions, preliminary test results consumption recent experiments, system's consumptions were measured in both Bollard...
Coastal upwelling is a wind-driven ocean process. It brings cooler, saltier, and usually nutrient-rich deep water upward to replace surface displaced offshore due Ekman transport. The nutrients carried up by are important for primary production fisheries. Ocean life can aggregate at the boundary between stratified water-the front. In an column, temperature, salinity, other properties much more homogeneous over depth than in water. Drawing on this difference, we set key measure...
