   1.                                                   We note disclosure on
page 7 and in a risk factor on page 21 entitled "We are involved in
                                                        litigation that may
adversely affect us, and may not be successful in our litigation related
                                                        to non-performing
Private Investment in Public Equity (   PIPE   ) investors" in which you
                                                        disclose that you
expected to receive approximately $330 million of proceeds in the
                                                        private placement that
closed on September 9, 2021 in connection with the Closing (the

but only received $110.3 million due to two investors that failed to
                                                        fulfill their funding
obligations under their subscription agreements with you. You further
                                                        disclose that you have

         order to enforce the funding obligations. Please revise to provide
information responsive
         to Item 103 of Regulation S-K about these legal proceedings, including
the name of the
         court or agency in which the proceedings are pending, the date
instituted, the principal
         parties thereto, a description of the factual basis alleged to
underlie the proceedings and
         the relief sought. As applicable, please also consider providing
updated disclosures
         regarding these proceedings.

Operations
Overview, page 101

2.       We note that you had increased operating costs in 2021 compared to
what you projected in
         the "Certain DeepGreen Projected Financial Information" disclosed in
your Form S-4
         (333-255118), and that such projections include capital expenditures
in 2022 and 2023 of
         $142 and $297 million, respectively, each greater than your cash and
cash equivalents at
         December 31, 2021. Further, we note that in your "Technical Report
Summary---Initial
         Assessment of NORI Property" filed as Exhibit 96.1 to your Form S-4,
this report
         discloses that NORI expects to spend $237 million on pre-project
activities between 2021
         and the date of the investment decision, which is expected June 30,
2023. However, you
         disclose on page 109 that you believe that your cash on hand at
December 31, 2021 of
         $84.9 million will be sufficient to meet your working capital and
capital expenditure
         requirements into the third quarter of 2023. Please disclose the basis
for your belief that
         you have sufficient cash to meet your capital requirements into the
third quarter of 2023,
         and, discuss any changes to your operating plans, including if you
continue to anticipate
         conducting enough pre-project activities to make the decision to mine
on the NORI
         Contract Area on or around June 30, 2023. Please update your
disclosure in Liquidity and
         Capital Resources, and elsewhere, to provide updated information about
the company   s
         financial position and further risks to the business operations and
liquidity in light of these
         circumstances.
3.       In light of the significant number of redemptions and the unlikelihood
that the company
         will receive significant proceeds from exercises of the warrants
because of the disparity
         between the exercise price of the warrants and the current trading
price of your common
         stock, expand your discussion of capital resources to address any
changes in the
         company   s liquidity position since the business combination. If the
company is likely to
         have to seek additional capital, discuss the effect of this offering
on the company   s ability
         to raise additional capital. Please also update your risk factors
section accordingly.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
