Development of Deep-Sea Biological Resources Exploitation Equipment

Feng Jingchun, Liang Jianzhen, Zhang Si, Yang Zhifeng, Zhu Zhenchang

Strategic Study of CAE 2020, Volume 22, Issue 6, Pages 67-75 doi: 10.15302/J-SSCAE-2020.06.009

Abstract:

The extreme environment in the deep sea gave birth to the largest ecosystem in the world that is far from known. The deepsea environment possesses a huge amount of biological resources with special functions. Exploitation equipment plays an important role in promoting the green, safe, and orderly development of the deep-sea biological resources. To clarify the characteristics and technical challenges of the equipment for deep-sea biological resources exploitation and explore its development directions and focus, we investigate the technical requirements of deep-sea biological resources exploitation, introduce the current status of the deep-sea biological resource exploitation equipment, and analyzes the challenges faced in the development of these equipment. To overcome the difficulties such as lack of unified standards, shortage of testing platforms, and deficiency in technology transformation, we propose several suggestions from the perspective of innovation system, general technology, transformation platform, and international cooperation, hoping to contribute to the sustainable development of the deep-sea biological resources from the equipment development perspective.

Synchronous observation of rising soluble bubble through quiescent solution

Yifu ZHANG , Shuai TIAN , Weizhong LI , Yongchen SONG ,

Frontiers in Energy 2009, Volume 3, Issue 3, Pages 307-312 doi: 10.1007/s11708-009-0028-7

Abstract: An experimental method using computer image processing technology (CIPT) was proposed to observe and investigate the velocity, deformation, heat and mass transfer, etc. of a rising soluble gas (CO) bubble through a quiescent hot water. A model was set up to describe the behavior of the bubble in a visual experimental system in which a high-speed camera rose instantaneously with the movement of the bubble. A series of trajectory videos about the bubble were recorded by a computer linked to the camera. The trajectory, volume changes and rate of mass transfer of the bubble were obtained by the CIPT. It is found that the single bubble follows a rolling trajectory at the initial stage when there is mass transfer. With the volume decreasing, the disturbed behavior of the bubble becomes tempered. When the rising velocity of the bubble reaches the maximum, the velocity is nearly at a constant. The experimental and analysis results show that this method is useful for the research on the mass transfer and the movement of rising bubbles in liquid.

Observation of black carbon aerosol in Beijing, 2003

LOU Shujuan, MAO Jietai, WANG Meihua

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 3, Pages 345-349 doi: 10.1007/s11783-007-0059-4

Abstract: The objective of this study was to determine the black carbon concentration in Beijing in 2003. The aerosol properties were measured using an Aethalometer and a tapered element oscillating microbalance (TEOM) on the roof of the Physics Building of Peking University (39.99º N, 116.31º E) from July to August 2003 and from November 2003 to January 2004. The average black carbon (BC) concentrations in the summer and winter were 8.80 and 11.4 μg/m, respectively. During winter, two different cyclone cut offs were installed at the inlet of an aethalometer. The BC mass concentration in TSP, PM, and PM were obtained. The results indicated that in winter aerosol, 90% of BC exited in PM and 82.6% of BC exited in PM. The BC in PM accounted for 5.11% of the PM mass.

The abundance, characteristics and diversity of microplastics in the South China Sea: Observation around

Hongzhe Chen , Sumin Wang , Huige Guo , Yunlong Huo , Hui Lin , Yuanbiao Zhang

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1, Pages 9-9 doi: 10.1007/s11783-021-1443-1

Abstract: Surrounded by emerging markets with considerable plastic consumption, the South China Sea has been a focus area of microplastic research. A survey on the floating microplastics (>0.3 mm) and microplastics ingested by fish and mollusks was conducted around three remote islands here. Compared with the results from several previous studies, a high abundance of floating microplastics (with a median of 1.9 × 105 items/km2 or 0.7 items/m3) was observed, revealing another “hot spot” for microplastics. Polyolefin, especially polypropylene, was the main component. The diversity index and evenness index were calculated and evaluated based on the composition of microplastics. The characteristic peaks of Raman spectra concerning pigmented microplastics were provided. Transparent sheets/films were predominant in the water sample, which was quite different from a similar study in this sea area (8.9% for film), and only 16.4% of floating microplastics (>0.3 mm) were fibers/lines, implying that the main sources of floating microplastics (>0.3 mm) might be household/agricultural consumption activities. The transparent fiber/line was also dominant in organisms. It is suggested that the main sources of microplastics ingested by organisms might be both fabric fibers and fishing/aquaculture.
