Scouting, Signaling, and Gatekeeping: Chinese Naval Operations in Japanese Waters and the International Law Implications

In October 2008, a month after Prime Minister Shinzo Abe of Japan stepped down and the more hawkish Taro Aso took office, a Chinese flotilla of four People\u27s Liberation Army Navy (PLAN) ships transited from west to east through Japan\u27s narrow Tsugaru Strait en route to the Pacific Ocean. The vessels were observed together in the Sea of Japan, headed east toward the strait, by a Japan Maritime Self-Defense Force (JMSDF) P-3C patrol aircraft; they were about twenty-five nautical miles west-southwest of Tappizaki, the cape at the northern tip of the Tsugaru Peninsula, where the Sea of Japan enters the Tsugaru Strait between the islands of Honshu and Hokkaido. The flotilla consisted of a Sovremennyy-class missile destroyer-one of four China bought from Russia between 1996 and 2002 a supply ship, and two Jiangkai frigates, one of which was a newly commissioned Jiangkai II. Apparently the Sovremennyy and one of the frigates had recently paid a friendly visit to a naval base in the Russian Far East before joining the other two Chinese naval vessels in the Sea of Japan and proceeding on through the strait to the Pacific Ocean.https://digital-commons.usnwc.edu/cmsi-red-books/1001/thumbnail.jp

Military Activities in the EEZ: A U.S.-China Dialogue on Security and International Law in the Maritime Commons

On the wall in the entranceway to the personal offices of the Commander, Pacific Fleet, there hangs prominently displayed a life-size portrait of Adm. Chester William Nimitz, the legendary architect of the American naval victory in the Pacific sixty-five years ago. The painting is specially lit, giving the admiral\u27s thoughtful gaze a lifelike glow as if he were present, judging the decisions and actions of his successors in command as these officers find means to preserve regional peace and guard American interests. In the painting\u27s background are the objects of naval war, standing as striking reminders of the heavy price in American blood and treasure paid for the nearly three generations since then during which the Pacific Ocean has been an American lake. It has been this freedom from serious threat that has provided room for American strategic and operational maneuver during the Korean conflict, the Vietnam War, and the Cold War, that has afforded an avenue for the movement of forces during conflicts in Iraq and Afghanistan, the capacity to deter conflict in East Asia, the access needed to assure the security of allies and partners, and the ability to provide support to populations devastated by disaster.https://digital-commons.usnwc.edu/cmsi-red-books/1006/thumbnail.jp

China\u27s Evolving Surface Fleet

The missile fast-attack craft and amphibious fleets of the People\u27s Liberation Army (PLA) Navy (PLAN) have undergone significant modernization over the past fifteen years. The capabilities of both categories of vessels have improved even if their actual numbers have not increased dramatically. Examined from the perspective of PLA doctrine and training, the missions of these forces represent the PLAN\u27s past, present, and future.https://digital-commons.usnwc.edu/cmsi-red-books/1013/thumbnail.jp

China Maritime Report No. 3: China’s Distant-Ocean Survey Activities: Implications for U.S. National Security

Today, the People’s Republic of China (PRC) is investing in marine scientific research on a massive scale. This investment supports an oceanographic research agenda that is increasingly global in scope. One key indicator of this trend is the expanding operations of China’s oceanographic research fleet. On any given day, 5-10 Chinese “scientific research vessels” (科学考查船) may be found operating beyond Chinese jurisdictional waters, in strategically-important areas of the Indo-Pacific. Overshadowed by the dramatic growth in China’s naval footprint, their presence largely goes unnoticed. Yet the activities of these ships and the scientists and engineers they embark have major implications for U.S. national security. This report explores some of these implications. It seeks to answer basic questions about the out-of-area—or “distant-ocean” (远洋)—operations of China’s oceanographic research fleet. Who is organizing and conducting these operations? Where are they taking place? What do they entail? What are the national drivers animating investment in these activities?https://digital-commons.usnwc.edu/cmsi-maritime-reports/1002/thumbnail.jp

Beyond the Wall: Chinese Far Seas Operation

This volume is the product of a groundbreaking dialogue on sea-lane security held between People\u27s Liberation Army (PLA) Navy and U.S. Navy scholars at the Naval War College in August 2013, with additional material from a related conference, China\u27s Far Seas Operations, hosted by the China Maritime Studies Institute in May 2012. At that time the political climate in China was uncertain, in the shadow of the Bo Xilai crisis and of the impending transition of power between the Hu and Xi regimes; accordingly the PLA Navy, though invited to participate in the Far Seas conference, ultimately declined to do so. This was not entirely surprising. Attempts by various agencies of the U.S. Navy up to that time to engage in discussions to advance maritime cooperation between China and the United States had been met with lukewarm responses at best. But at a maritime security dialogue in Dalian in September 2012 Senior Capt. Zhang Junshe of the PLA Navy Research Institute, a key contributor to this volume and to the success of the academic cooperation between our two institutes, approached Peter Dutton to tell him that everything had changed.https://digital-commons.usnwc.edu/cmsi-red-books/1012/thumbnail.jp

Abundance, distribution, and habitat of leatherback turtles (Dermochelys coriacea) off California, 1990−2003

Leatherback turtles (Dermochelys coriacea) are regularly seen off the U.S. West Coast, where they forage on jellyfish (Scyphomedusae) during summer and fall. Aerial line-transect surveys were conducted in neritic waters (<92 m depth) off central and northern California during 1990−2003, providing the first foraging population estimates for Pacific leatherback turtles. Males and females of about 1.1 to 2.1 m length were observed. Estimated abundance was linked to the Northern Oscillation Index and ranged from 12 (coefficient of variation [CV] =0.75) in 1995 to 379 (CV= 0.23) in 1990, averaging 178 (CV= 0.15). Greatest densities were found off central California, where oceanographic retention areas or upwelling shadows created favorable habitat for leatherback turtle prey. Results from independent telemetry studies have linked leatherback turtles off the U.S. West Coast to one of the two largest remaining Pacific breeding populations, at Jamursba Medi, Indonesia. Nearshore waters off California thus represent an important foraging region for the critically endangered Pacific leatherback turtle

China Near Seas Combat Capabilities

The capstone U.S. Defense Department study on the future operational environment declares, China\u27s rise represents the most significant single event on the international horizon since the collapse of the Cold War. Understanding and assessing changes in China\u27s traditionally defensive naval strategy, doctrine, and force structure are of obvious importance to the U.S. Navy (USN) and other Pacific navies concerned with the possible security implications of that rise. This chapter examines the development of the Chinese navy\u27s Houbei (Type 022) fast-attack-craft force and its roles and missions in China\u27s near seas and discusses implications for the U.S. Navy and other navies in the region.https://digital-commons.usnwc.edu/cmsi-red-books/1010/thumbnail.jp

China Maritime Report No. 7: Gwadar: China\u27s Potential Strategic Strongpoint in Pakistan

This China Maritime Report on Gwadar is the second in a series of case studies on China’s Indian Ocean “strategic strongpoints” (战略支点). People’s Republic of China (PRC) officials, military officers, and civilian analysts use the strategic strongpoint concept to describe certain strategically valuable foreign ports with terminals and commercial zones owned and operated by Chinese firms.https://digital-commons.usnwc.edu/cmsi-maritime-reports/1006/thumbnail.jp

China Maritime Report No. 6: Djibouti: China\u27s First Overseas Strategic Strongpoint

This China Maritime Report on Djibouti is the first in a series of case studies on China’s “overseas strategic strongpoints” (海外战略支点). The strategic strongpoint concept has no formal definition, but is used by People’s Republic of China (PRC) officials and analysts to describe foreign ports with special strategic and economic value that host terminals and commercial zones operated by Chinese firms.https://digital-commons.usnwc.edu/cmsi-maritime-reports/1005/thumbnail.jp

mockrobiota: a Public Resource for Microbiome Bioinformatics Benchmarking.

Mock communities are an important tool for validating, optimizing, and comparing bioinformatics methods for microbial community analysis. We present mockrobiota, a public resource for sharing, validating, and documenting mock community data resources, available at http://caporaso-lab.github.io/mockrobiota/. The materials contained in mockrobiota include data set and sample metadata, expected composition data (taxonomy or gene annotations or reference sequences for mock community members), and links to raw data (e.g., raw sequence data) for each mock community data set. mockrobiota does not supply physical sample materials directly, but the data set metadata included for each mock community indicate whether physical sample materials are available. At the time of this writing, mockrobiota contains 11 mock community data sets with known species compositions, including bacterial, archaeal, and eukaryotic mock communities, analyzed by high-throughput marker gene sequencing. IMPORTANCE The availability of standard and public mock community data will facilitate ongoing method optimizations, comparisons across studies that share source data, and greater transparency and access and eliminate redundancy. These are also valuable resources for bioinformatics teaching and training. This dynamic resource is intended to expand and evolve to meet the changing needs of the omics community
