In China seas, it is red Noctiluca scintillans (RNS) dominated. During recent years, RNS bloom events in China seas have been increasing, either in terms of frequency or intensity. Efficient monitoring approaches are highly demanded. Here in this study, an intense bloom of RNS occurring in the western Taiwan Strait in late April, 2020 was investigated. Microscopic analysis of water samples in the bloom area showed maximum RNS density as high as 5.6 \u00d7 10 5 cells\/L, while chlorophyll a (Chla) fluorometer detected no difference in and out of the bloom area. Similarly, Chla concentration in the whole study area from MODIS was low. These were consistent with the notion that RNS was heterotrophic, containing no pigments for photosynthesis. However, pCO 2 decreased substantially (~50-100 matm) in the bloom area, suggesting usage of CO 2 for photosynthesis. It looks like that autonomous detection of RNS bloom is still challenging, in particular from space. An integrated approach with optical and chemical proxies would be necessary. And, more specific in situ surveys of RNS blooms and RNS culture experiments are certainly desired.<\/p>\n Jingyu Wu<\/b><\/a><\/span>, Xiamen University, wjy@xmu.edu.cn<\/p>\n Shaoping Shang, Xiamen University, spshang@xmu.edu.cn\u00a0<\/span><\/p>\n Yanshuang Xie, Xiamen University, xys_0614@126.com\u00a0<\/span><\/p>\n Ke Liu, Xiamen University, kliu@xmu.edu.cn<\/p>\n Famei Lei, Xiamen University, lfm101659@163.com\u00a0<\/span><\/p>\n Guomei Wei, Xiamen University, weiguomei@163.com\u00a0<\/span><\/p>\n Qiang Dong, Xiamen University, dongqiang@xmu.edu.cn\u00a0<\/span><\/p>\n Zhigang He, Xiamen University, zghe@xmu.edu.cn<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ custom_padding_last_edited=”on|tablet” _builder_version=”4.14.7″ _module_preset=”default” background_enable_color=”off” background_image=”https:\/\/oceanopticsconference.org\/wp-content\/uploads\/2022\/01\/oo22-banner-bckd.jpg” custom_padding=”0px||11px||false|false” custom_padding_tablet=”0px||11px||false|false” custom_padding_phone=”||27px||false|false” global_module=”2766″ saved_tabs=”all” locked=”off” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||8px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_social_media_follow use_icon_font_size=”on” icon_font_size=”19px” _builder_version=”4.16″ _module_preset=”default” custom_button=”on” text_orientation=”right” custom_margin=”-10px||11px||false|false” custom_margin_tablet=”-9px||5px||false|false” custom_margin_phone=”-9px||5px||false|false” custom_margin_last_edited=”on|tablet” global_colors_info=”{}” button_text_size__hover_enabled=”on|desktop” theme_builder_area=”post_content”][et_pb_social_media_follow_network social_network=”facebook” url=”https:\/\/www.facebook.com\/OceanOpticsConference\/” _builder_version=”4.16″ _module_preset=”default” background_color=”#9b9b9b” background_enable_color=”on” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”#0C71C3″ background_enable_color__hover=”on” theme_builder_area=”post_content” follow_button=”off” url_new_window=”on”]facebook[\/et_pb_social_media_follow_network][et_pb_social_media_follow_network social_network=”twitter” url=”https:\/\/twitter.com\/OceanOpticsConf” _builder_version=”4.16″ _module_preset=”default” background_color=”#9b9b9b” background_enable_color=”on” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”#0C71C3″ background_enable_color__hover=”on” theme_builder_area=”post_content” follow_button=”off” url_new_window=”on”]twitter[\/et_pb_social_media_follow_network][\/et_pb_social_media_follow][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ use_custom_gutter=”on” gutter_width=”2″ _builder_version=”4.16″ _module_preset=”default” custom_padding=”13px||34px|0px||” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_3″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.16″ _module_preset=”default” header_font_size=”26px” header_2_font=”|||on|||||” header_2_text_align=”center” header_2_text_color=”#FFFFFF” header_2_font_size=”21px” text_orientation=”center” custom_margin=”||5px|||” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_text_color=”#FFFFFF” link_font=”||||on||||” link_text_color=”#FFFFFF” header_2_text_color=”#FFFFFF” max_width=”300px” module_alignment=”center” custom_margin=”||||false|false” custom_margin_tablet=”||-3px||false|false” custom_margin_phone=”” custom_margin_last_edited=”on|tablet” custom_padding_tablet=”||||false|false” custom_padding_phone=”||32px||false|false” custom_padding_last_edited=”on|phone” global_colors_info=”{}” link_text_color__hover_enabled=”on|hover” link_text_color__hover=”#a8a8a8″ theme_builder_area=”post_content”]<\/p>\n Sign up to receive email updates to be sure to catch all the meeting news.
