DARPA: Five Teams of Researchers Will Help DARPA Detect Undersea Activity by Analyzing Behaviors of Marine Organisms

Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA's Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. This new, bio-centric PALS technology will augment the Department of Defense's existing, hardware-based maritime monitoring systems and greatly extend the range, sensitivity, and lifetime of the military's undersea surveillance capabilities.

DARPA first announced the PALS program in February 2018 with the goal of incorporating biology into new solutions for monitoring adversary movements across the seemingly endless spaces of the world's oceans and seas. Ubiquitous, self-replicating, self-sustaining sea life is adaptable and highly responsive to its environment, whereas maritime hardware is resource intensive, costly to deploy, and relatively limited in its sensing modalities. According to PALS program manager Lori Adornato, “Tapping into the exquisite sensing capabilities of marine organisms could yield a discreet, persistent, and highly scalable solution to maintaining awareness in the challenging underwater environment.”

The DARPA-funded PALS teams must develop or apply technologies to record stimulus responses from observed organisms, and develop combined hardware and software systems that interpret those responses, screen out false positives, and transmit analyzed results to remote end users. The teams' solutions will incorporate technologies such as hydrophones, sonar, cameras, and magnetic, acoustic, and kinetic sensors.

  • The team led by Northrop Grumman Corporation, under principal investigator Robert Siegel, will record and analyze acoustics from snapping shrimp and optical activity by bioluminescent organisms.
  • The team led by the Naval Research Laboratory, under principal investigator Lenny Tender, will integrate microbial organisms into a sensing platform to detect and characterize biological signals from natural microorganisms that respond to the magnetic signatures of underwater vehicles.
  • The team led by Florida Atlantic University, under principal investigator Laurent Cherubin, will record and analyze vocalization cues from goliath grouper in tropical and subtropical environments.
  • The team led by Raytheon BBN Technologies, under principal investigator Alison Laferriere, will use snapping shrimp as sources of opportunity for long-range detection, classification, and tracking of underwater vehicles.
  • The team led by the University of Maryland Center for Environmental Science, under principal investigator David Secor, will tag black sea bass with sensors to track the depth and acceleration behaviors of schools of fish that are perturbed by underwater vehicles.

DARPA is also funding the Naval Undersea Warfare Center, Division Newport, under principal investigator Lauren Freeman, to develop a seafloor system that uses a hydrophone array and acoustic vector sensor to continuously monitor ambient biological sound in a reef environment for anomalies. The system will analyze changes in the acoustic signals radiated by the natural predator-avoidance response of coral reef ecosystem biota, which could offer an indirect mechanism to detect and classify underwater vehicles in near-real time.

DARPA conceived of PALS as a four-year research program with the expectation that researchers will be able to publish results for review by the broader scientific community. However, if DARPA identifies any of the data, results, or technical specifications as controlled unclassified information, DARPA will require the PALS researchers to protect them to prevent proliferation outside of official channels.

  • Norway’s allies share their views on the country’s new defense plan

    Norway’s allies share their views on the country’s new defense plan

    By: Stephen J. Flanagan and James Black As countries around the world grapple with the unfolding coronavirus pandemic, the wider business of government continues. Norway's Ministry of Defence will shortly publish its next Long Term Plan, which will then be debated by parliament. The plan outlines how the Armed Forces, in tandem with other elements of government and society, can best address the threats to Norway from hostile states, terrorists, and fragile and failing states. The plan also examines how to bolster national resilience to deal with other risks including hybrid warfare, climate change and pandemics. A new Rand report, commissioned by the MoD to inform its strategy and policy development, offers perspectives from its closest allies on the emerging security challenges and strategic options facing Norway. We found broad alignment of Norwegian and allied assessments across Denmark, France, Germany, the U.K., the U.S. and NATO institutions, but some enduring differences in emphasis and priorities. Other allies recognize Norway as punching above its weight and playing a critical role in the defense of the North Atlantic and High North. At the same time, our research concludes there is no time for complacency. Norway's key allies agree that the most significant threat in the High North is not a crisis directed against Norway itself. The more plausible danger is “horizontal escalation” — a crisis elsewhere in Europe rapidly growing into a wider conflict that threatens Norwegian waters, airspace and territory. Russia continues to demonstrate hostile intent, and its military capabilities threaten the ability of Norway and its allies to operate military forces, secure critical infrastructure and protect civilian populations. The collapse of the Intermediate-Range Nuclear Forces Treaty in 2019 brings an increased threat from medium-range ballistic missiles, requiring Norwegian and allied defense planners to adjust to new threats to the homeland and region. Improvements in the Russian Northern Fleet, including surface vessels and submarines armed with modern cruise missiles, also pose an increased threat to NATO operations in the Norwegian Sea, to undersea internet cables and to sea lines of communication essential to reinforcing Norway from North America or Europe in the event of any conflict. There is also strong consensus on the enduring threats posed by terrorism, nonstate actors and challenges such as climate change in the Arctic. While all allies recognize the need to consider the strategic implications of a rising China, the United States sees China as a more direct and imminent security threat. Allies also welcome Norway's contributions to missions on NATO's eastern and southern flanks. Allies perceive Norway as having an impressive mix of high-end capabilities for a country of its size and a mature total defense concept — its strategy for engaging all elements of society in national defense. These capabilities and commitments, coupled with a well-respected approach to strategy development, have allowed Norway to have significant influence on strategic thinking within NATO. Nevertheless, significant security challenges remain, and to address them our report suggests a number of options for Norwegian leaders to consider: Strengthen deterrence in Norway: Expand surveillance and reconnaissance capabilities; increase the military posture in northern Norway; enhance the protection of bases and forces against air and missile threats; maximize the F-35 fighter jet's potential to aid joint operations; and prepare for operations in contested cyber, space and electromagnetic environments. Expand capacity to receive allied reinforcements: Build on lessons from the joint Trident Juncture 2018 exercise, which allies viewed as an important milestone but not a full stress test; pursue increasingly challenging training scenarios; ensure sufficient pre-positioned stocks of consumables and equipment; upgrade and expand infrastructure along with concepts for dispersing forces to prevent attack; and deepen cooperation to enhance military mobility and interoperability. Explore concepts to hold potential adversaries at risk: Invite allies with more advanced reconnaissance and deep-attack systems to deploy them to Norway periodically; develop longer-range weapons for Norwegian forces; explore the utility of low-cost, unmanned assets; collaborate with key allies on concepts to deny adversaries access to the sea and to better project forces onto the littoral; and refine parallel strategic communications to control escalation. Enhance national and societal resilience: Test and refine Norway's whole-of-government approach and the mechanisms for civil support to the military; contribute to NATO's strategy for addressing hybrid threats, such as disinformation, economic pressure and cyberattacks; and explore further measures to enhance collective preparedness and will to fight. Solidify Norwegian contributions to NATO and partners: Continue contributions to NATO operations beyond the north; help to address variations in defense expenditure across all NATO nations and rebalance trans-Atlantic burden-sharing; promote deeper NATO cooperation with Sweden and Finland; and use innovation and industry to enable influence within NATO. Other countries can learn from how Norway chooses to tackle these emerging challenges, and they can benefit from its lessons learned, particularly with respect to the total defense concept. Pursuit of some of these options, along with the Norwegian government's ongoing efforts to seek allied views, could help enhance deterrence in the north and overall NATO defense. Stephen J.

  • Members of Congress look to make AI a priority

    Members of Congress look to make AI a priority

    By: Jessie Bur Congress and the executive branch need to make a more concerted effort to address and prepare for the rise of artificial intelligence, Reps. Will Hurd, R-Texas, and Robin Kelly, D-Ill., said in a white paper released Sept. 25. The congressmen, who serve as the chairman and ranking member of the House IT Subcommittee, compiled information gathered in past congressional hearings and meetings with experts to argue for the criticality of federal input in the many facets of AI. “In light of that potential for disruption, it's critical that the federal government address the different challenges posed by AI, including its current and future applications. The following paper presents lessons learned from the Subcommittee's oversight and hearings on AI and sets forth recommendations for moving forward,” Hurd and Kelly wrote. “Underlying these recommendations is the recognition the United States cannot maintain its global leadership in AI absent political leadership from Congress and the executive branch. Therefore, the Subcommittee recommends increased engagement on AI by Congress and the administration.” According to the White Paper, under current trends the United States is soon slated to be outpaced in research and development investments by countries like China that have prioritized artificial intelligence investment. “Particularly concerning is the prospect of an authoritarian country, such as Russia or China, overtaking the United States in AI. As the Subcommittee's hearings showed, AI is likely to have a significant impact in cybersecurity, and American competitiveness in AI will be critical to ensuring the United States does not lose any decisive cybersecurity advantage to other nation-states,” Hurd and Kelly wrote. Hurd characterized the Chinese investment in AI as a race with the U.S. “It's a race, we all know this, and one of the things we need [is] a national strategy, similar to what we've seen in the conversations around quantum computing yesterday at the White House. What we saw almost a decade ago when it came to nanotechnology. And part of that strategy does include increasing basic research, opening up data sets and making sure the U.S. is playing a part, leader on ethics when it comes to artificial intelligence,” said Hurd in a Sept. 25 press call. The paper applauded current investments in R&D, such as the Defense Advanced Research Projects Agency's creation of the Artificial Intelligence Exploration program, and encouraged government hosting more “Grand Challenges” like those conducted by DARPA to encourage outside-government innovation. “I do believe the federal government has a role, because we're sitting on data sets that could be used as a backbone of a Grand Challenge around artificial intelligence,” said Hurd, who added that the National Oceanic and Atmospheric Administration, healthcare agencies and many other components of the federal government possess the data to administer meaningful AI competitions. “I think this would be a maybe a great opportunity for a public private partnership,” added Kelly on the press call. The paper also identified four primary challenges that can arise as AI becomes more prevalent: workforce, privacy, bias and malicious use. AI has the potential to both put portions of the workforce out of a job as more tasks become automated and increase the number of jobs for those trained to work with artificial intelligence. Hurd and Kelly called on the federal government to lead the way in adapting its workforce by planning for and investing in training programs that will enable them to transition into AI work. As with many technologies, AI has the potential to infringe on privacy, as intelligent products or systems such as virtual assistants constantly collect data on individuals. That data could be exploited by both the company that created the technology and hackers looking to steal personal information. “The growing collection and use of personal data in AI systems and applications raises legitimate concerns about privacy. As such, federal agencies should review federal privacy laws, regulations, and judicial decisions to determine how they may already apply to AI products within their jurisdiction, and—where necessary—update existing regulations to account for the addition of AI,” Hurd and Kelly wrote. The white paper also calls on federal agencies to make government data more available to the public for AI experimentation, while also ensuring that any AI algorithms used by agencies to “make consequential decisions about individuals” are “inspectable” to ensure that they operate without coded bias. According to Hurd, the question of whether and how that inspectable information would be made available to the public still needs to be asked. Finally, Hurd and Kelly called on government entities to consider how AI may be used to perpetuate cyber attacks or otherwise cause harm. However, while recommending that agencies look to existing regulation and statute and some limited changes to those statutes, the paper encouraged a similar hands off approach that the federal government took to the development of the internet. “The government should begin by first assessing whether the risks to public safety or consumers already fall within existing regulatory frameworks and, if so, consideration should be made as to whether those existing frameworks can adequately address the risks,” Hurd and Kelly wrote. “At minimum, a widely agreed upon standard for measuring the safety and security of AI products and applications should precede any new regulations. A common taxonomy also would help facilitate clarity and enable accurate accounting of skills and uses of AI.” https://www.federaltimes.com/federal-oversight/congress/2018/09/25/members-of-congress-look-to-make-ai-a-priority
