SUPPLEMENTARY INFORMATION:

Introduction

    Over 500 subsea fiber optic telecommunications cables, including 
both installed and planned cables, cover nearly all ocean regions 
including multiple high Arctic cables. NSF is investigating the 
implementation of a modern subsea fiber optic telecommunications cable 
connecting the largest U.S. Antarctic Program (https://www.usap.gov/) 
research facility, McMurdo Station (77[deg]50'47'' S,166[deg]40'06'' E) 
(https://www.usap.gov/videoclipsandmaps/mcmwebcam.cfm?t=1), with either 
New Zealand or Australia. Although the main scope of the installation 
is to provide advanced high-speed, low delay telecommunications, this 
cable will contain additional point sensors (e.g., SMART--Science 
Monitoring And Reliable Telecommunications) and/or distributed sensing 
infrastructure, enabling for the first time myriad investigations 
across a broad range of scientific disciplines.
    The NSF Directorates for Geosciences (GEO), Computer and 
Information Science and Engineering (CISE), and Technology, Innovation, 
and Partnerships (TIP) have identified the potential subsea cable as an 
opportunity for transformational changes in the conduct of science, 
vast improvements in telecommunications capability supporting 
Antarctica, and innovative

[[Page 92179]]

public-private partnerships linking science and technology.
    Additionally, the cable would have the ability to accommodate 
additional, multiple forms of distributed fiber optic sensing that are 
advancing rapidly in technology maturity (e.g., Distributed Acoustic 
Sensing, Distributed Temperature Sensing, State of Polarization, etc.). 
Preliminary cable routes have been established using standard subsea 
cable industry best practices that avoid areas posing high geophysical 
risk, as well as initial feedback from the scientific community via a 
virtual workshop in 2021, producing a broad corridor where 
opportunities exist to adjust the final route to best align with Earth 
science areas of high science research interest.
    Further, science research supported by the cable sensors is of 
societal relevance on a global scale for a number of reasons, such as 
(1) filling significant knowledge gaps of key global ocean processes 
and trends for improved understanding and monitoring climate change, 
including ocean heat transport, CO2 sequestration, and sea 
level rise; (2) regional seismic monitoring and early warning of 
potential tsunami seismic events; (3) global measurements of 
geophysical Earth structure; and (4) developing the technological 
capabilities to enhance other global telecommunications infrastructure 
for scientific research and human benefit.

Science Workshop

    In late June 2021, the NSF Directorate for Geosciences, Office of 
Polar Programs (GEO/OPP) (https://www.nsf.gov/div/index.jsp?div=OPP) 
and Directorate for Computer Information Science and Engineering, 
Office of Advanced Cyberinfrastructure (CISE/OAC) (https://new.nsf.gov/cise/oac), jointly funded a research community-led science workshop 
(https://www.pgc.umn.edu/workshops/antarctic-cable/) to review the 
scientific benefits of a sensor-enabled subsea fiber cable. The 
Workshop endorsed the cable concept and noted that existing technology 
and cable systems make it feasible. The Workshop concluded that the 
proposed activity would benefit Antarctic science research by both 
increasing telecommunications capacity and including new science 
sensors in the cable design.
    The Workshop's Executive Summary captured four primary findings:
    Finding 1: Existing and future Antarctic research would be 
significantly enhanced if bandwidth limitations were eliminated through 
the availability of a modern submarine cable system.
    Finding 2: A new submarine cable could be constructed with embedded 
instrumentation (a Scientific Monitoring And Reliable 
Telecommunications, or SMART, cable) that would itself enable 
meaningful new research and understanding of the region.
    Finding 3: Robust bandwidth for interpersonal connectivity for 
scientists and staff, if thoughtfully approached, could be 
transformative for research and work functions, participation in 
Antarctic science, education, engagement, and community wellbeing.
    Finding 4: Construction of a new SMART cable that provides 
essentially unlimited bandwidth to McMurdo is feasible and could also 
serve as the platform to extend connectivity to deep-field research 
sites as well as critical research programs at Amundsen-Scott South 
Pole Station. This level of connectivity can transform the science and 
research platforms for future generations.

Feasibility Study

    In response to the 2021 Science Workshop, NSF contracted a 
comprehensive preliminary concept/feasibility study (known as a Desktop 
Study, or DTS https://gbs1.com/desktop-studies/), incorporating the 
unique attributes of implementing a sensor-enabled cable to Antarctica. 
The public version of the McMurdo Cable DTS (https://www.nsf.gov/geo/opp/documents/NSF_Public%20Release%20DTS_Final.pdf) was released in 
October 2023. NSF also provided a summary and news release (https://www.nsf.gov/news/news_summ.jsp?cntn_id=308774&org=OPP).
    The DTS addresses two proposed routes for comparison: (1) McMurdo 
Station to Sydney, Australia and (2) McMurdo Station to Invercargill, 
New Zealand. It includes brief assessments of optional extensions from 
the main cable routes to Macquarie Island for potential interconnection 
to the Australian research station located there and to nearby 
international research stations located in the Western Ross Sea/Terra 
Nova Bay area. More details on the proposed routes including landing 
sites and relevant diagrams can be found in section 2 of the DTS.
    The study Executive Summary summarizes the key study results in a 
comparison of the two routes considered.
    Both routes were considered technically feasible with the following 
observations:
    (1) The NZ route is 1,500 km shorter and thus considerably more 
economical.
    (2) The Australian route has additional geophysical risk to the 
cable arising from a crossing of the seismically active Macquarie Ridge 
Complex to the north of Macquarie Island.
    (3) The New Zealand route covers more regions of science interest 
as indicated by science researcher input to the study. Seismologist 
interests obtained during the study proposed cable branching units 
located at 60[deg]S and 50[deg]S for future sea bottom seismometer 
instruments tapping the cable's power and communications.
    (4) The risk from ice scour appears reasonable based upon detailed 
near-shore bathymetry--the Antarctic SMART Cable landing risk 
mitigation uses standard subsea cable landing techniques called 
Horizontal Directional Drilling (HDD). Bathymetry and iceberg keel 
depth studies pertaining to the cable route transit across the Ross Sea 
continental shelf yield a similar low risk assessment.
    (5) Environmental assessments and permitting will be a significant 
component of future work, as is the case with all subsea cable 
projects, and will include the Antarctic Treaty Committee on 
Environmental Protection protocols. Coordination with the Committee for 
the Conservation of Antarctic Marine Living Resources (CCAMLR) will be 
needed as the proposed cable route transits the CCAMLR governed Marine 
Protected Areas in the Ross Sea region.

Subsea Cable Industry Considerations

    A subsea cable installation represents a substantial economic 
investment. As such, modern subsea telecommunications cables are 
designed with a 25-year or greater lifetime and thus are designed for 
high reliability and low maintenance. The introduction of SMART sensors 
into commercial subsea telecommunications cables is a new phenomenon, 
with the Government of Portugal-sponsored Atlantic CAM cable (https://www.infraestruturasdeportugal.pt/pt-pt/ip-e-asn-assinam-contrato-para-construcao-de-novo-anel-cam) and the TAMTAM cable connecting New 
Caledonia and Vanuatu (https://www.soest.hawaii.edu/soestwp/announce/news/contract-signed-vanuatu-new-caledonia/) being the first examples. 
The introduction of sensors into a standard telecommunications cable 
meeting scientific requirements and inherent cable design life/
reliability requirements represents both a new market opportunity and a 
new technical frontier for industry that will influence the design and 
adoption of SMART sensors. Point sensors also complement and enhance 
commercially available cable sensing technologies such as distributed 
fiber sensing.

Location of the SMART Cable, Sensors, and Future Cable Expansion

    For some segments of the cable, it may be possible to shift the 
cable's path slightly in some locations to accommodate additional 
science or enable long-term monitoring of specific scientific targets. 
Further, depending upon the final technological solution(s) for how 
sensor units will be incorporated into the cable, there may be 
opportunities to select the locations of some of the sensor modules. 
Finally, the cable may be able to include one or more Branching Units 
(BUs). A BU can be used for multiple purposes, such as adding another 
cable branch, attaching a localized device, or providing an entry point 
for including a localized network of sensors focused on a specific area 
or areas.

Partnerships and the Project

    The Whitepaper (https://goosocean.org/news/un-ocean-decade-challenge-7-white-paper-a-roadmap-for-the-observing-system-we-need/) 
addressing Challenge 7 (``Expand the Global Ocean Observing System'') 
from the UN IOC/UNESCO Decade of Ocean Science for Sustainable 
Development (2021-2030) (``Ocean Decade 2030'') program indicates that 
significant investments will be needed to meet the challenges for 
global ocean observation goals while current investments and mechanisms 
are inadequate. There is a clear call for multi-sector engagements such 
as public-private partnerships and international collaborations for a 
``new economic thinking'' to provide the resources needed.
    29. What private and/or public sector groups (e.g., academic, non-
profit, industry, etc.) do you think may have an active interest in 
partnership activities with NSF for aspects of the cable system 
development?

Contribution of the Antarctic SMART Cable To Resolve Global Challenges

    30. Beyond the potential direct benefits to support science in the 
Antarctic and the region covered directly by the Antarctic SMART Cable, 
there may be broader benefits to developing the Antarctic SMART Cable. 
In your view, what are the global, national, and societal benefits of 
this cable?

Future Science Workshop

    31. A successor science workshop is being considered for 2025 to 
build upon and extend the work of the June 2021 workshop and this 
Electronic On-Line Submission. How interested would you be in attending 
virtually or in-person, provided full or partial travel expenses could
