The name of the issuer is SAExploration Holdings, Inc., a Delaware corporation (the “Issuer”).  The address of the Issuer’s principal executive offices is 1160 Dairy Ashford Rd., Suite 160, Houston, Texas 77079, United States of America.  This Schedule 13D relates to the Issuer’s common stock, $0.0001 par value (the “Shares”).
Item 2. Identity and Background.
(a), (f) This Schedule 13D is being filed jointly by (i) Whitebox Advisors LLC, a Delaware limited liability company (“WA”), (ii) Whitebox General Partner LLC (“WB GP”), (iii) Whitebox Multi-Strategy Partners, LP, a British Virgin Islands limited partnership (“WMP”), (iv) Whitebox Credit Partners, LP, a British Virgin Islands limited partnership (“WCP”), and (v) the Executive Officers and Board of Managers of WA and the members of the Board of WB GP, the names and citizenship of which are set forth in Exhibit B and Exhibit C, respectively (collectively, the “Reporting Persons”).
(b)

The principal business address for each of
WA and WB GP is 3033 Excelsior Boulevard, Suite 300, Minneapolis, Minnesota 55416.

The principal business address of WMP is c/o
Estera Corporate Services (BVI) Limited, Jayla Place, Wickhams Cay 1, PO Box 3190, Road Town, Tortola, British Virgin Islands VG1110.

The principal business address of WCP is c/o

(c) WA manages and advises private investment funds, including WMP and WCP (the “WA Private Funds”).  WB GP serves as general partner of private investment funds, including WMP and WCP.  The principal business of WMP and WCP is investments.  The principal businesses of the Executive Officers and Board of Managers of WA and the members of the Board of WB GP, are set forth in Exhibit B and Exhibit C, respectively.
(d) None of the Reporting Persons have, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).
(e)

Except as set forth below in this Item 2(e)
none of the Reporting Persons have, during the last five years been a party to a civil proceeding of a judicial or administrative
body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

In April 2014, WA received a confidential information
inquiry from the Securities and Exchange Commission (the “SEC”) in connection with the purchase of shares in a secondary
public offering which occurred in 2012. WA fully cooperated with the SEC and voluntarily reviewed historical trading activity to
identify any other potential instances of inadvertent violations of Rule 105 of Regulation M under the Exchange Act (“Rule
105”). Based on this review, WA identified four additional instances in 2011 and 2012 where WA participated in a secondary
offering during a restricted period. All of these instances were voluntarily disclosed to the SEC. The violations allegedly occurred
between January 2011 and June 2012. Rule 105 generally prohibits purchasing an equity security in a registered follow-on public
offering if the purchaser sold short the same security during the shorter of the period: (1) beginning five business days before
the pricing of the offered securities and ending with such pricing; or (2) beginning with the initial filing of a registration
statement or notification on Form 1-A or Form 1-E and ending with the pricing.

In July 2014, WA voluntarily submitted to an
offer of settlement with respect to the five alleged violations of Rule 105, without admitting or denying the SEC’s allegations.
The SEC accepted the offer of settlement, and imposed a cease-and-desist order from future violations of Rule 105. The settlement
involved the payment by WA of disgorgement of $788,779, prejudgment interest of $48,553.49 and a civil money penalty of $365,592.83
(for a total of $1,202,925.30) to the U.S. Treasury.

Exhibit V hereto and is incorporated herein by reference.

Series
A Preferred Shares

On January
29, 2018
(the “Settlement Date”), the Issuer issued 31,669 shares of the
Issuer’s
Series A Preferred Shares in connection with the consummation of the 2018 Exchange Offer in a private placement
exempt from registration under the Securities Act.

Pursuant to
the Certificate of Designations of 8.0% Cumulative Perpetual Series A Preferred Stock, each Series A Preferred Share gives the
holder thereof the right to convert Series A Preferred Shares into shares of Common Stock at any time after the third anniversary
of the Settlement Date, subject to certain exceptions, including receipt of shareholder approval and a limitation on the ability
of certain holders to convert Series A Preferred Shares if it would cause such holder to beneficially own in excess of 9.99% of
the outstanding Common Stock. The Series A Preferred Shares have an initial conversion rate (the “Series A Conversion Rate”)
of 3,271.4653 shares of Common Stock per Series A Preferred Share, subject to customary anti-dilution adjustments. Based on the
initial Series A Conversion Rate, approximately 103,702,178 shares of Common Stock would be issuable upon conversion of all of
the outstanding Series A Preferred Shares.

The annual dividend
on each Series A Preferred Share is 8.0% and is payable quarterly, in arrears, on each January 1, April 1, July 1 and October 1
of each year, commencing on April 1, 2018. No dividends will accrue or accumulate prior to January 29, 2018. If the Issuer’s free
cash flow for the twelve-month period ending on the fifteenth day prior to each dividend period is $15 million or less, then the
Issuer will pay dividends on the Series A Preferred Shares by increasing the amount of Series A Preferred Shares held in book entry
form or, in the case of certificated Series A Preferred Shares, issuing new certificated Series A Preferred Shares, in each case,
in an amount equal to such dividend. Except as provided in the previous sentence, the Issuer will pay dividends in cash.

Except as required
by law or the Issuer’s Third Amended and Restated Certificate of Incorporation, as amended, holders of the Series A Preferred Shares
will have no voting rights, except for the right to consent to the Issuer’s creation, authorization or issuance of any class or
series of stock senior to the Series A Preferred Shares (or any security convertible into stock senior to the Series A Preferred
Shares) or stock on parity with the Series A Preferred Shares (or any security convertible into stock on parity with the Series
A Preferred Shares), and amendments to the Issuer’s constituent documents that would adversely affect the rights, preferences,
privileges or voting rights of the holders of the Series A Preferred Shares.

Upon a change
of control and subject to certain exceptions, the Issuer may cause all outstanding Series A Preferred Shares to be converted into
Common Stock at the then-prevailing Series A Conversion Rate, subject to certain exceptions, including receipt of shareholder approval,
and limitations, including a limitation on the ability of the Issuer to convert a Series A Preferred Share if it would cause a
holder thereof to beneficially own in excess of 9.99% of the outstanding Common Stock.

At any time
following the Settlement Date, the Issuer may redeem each Series A Preferred Share at a price equal to $1,000 per Series A Preferred
Share, subject to certain adjustments, plus accumulated and unpaid dividends on such share to, but excluding the redemption date.

The
summary of the Issuer’s
Certificate of Designations of 8.0% Cumulative Perpetual Series A Preferred Stock set
forth above does not purport to be complete and is qualified in its entirety by reference to the Issuer’s
Certificate of
Designations for the Series A Preferred Shares, dated as of January 29, 2018, a copy of which
is being filed as Exhibit W hereto and is incorporated herein by reference.

Series
B Preferred Shares

On the Settlement
Date, the Issuer issued 855,195 shares of the Issuer’s Series B Preferred Shares in
connection with the consummation of the 2018 Exchange Offer in a private placement exempt from registration under the Securities
Act.

Pursuant to
the Certificate of Designations of Mandatorily Convertible Series B Preferred Stock, each Series B Preferred Share is mandatorily
convertible by the Issuer at any time after the third anniversary of the Settlement Date, subject to certain exceptions, including
receipt of shareholder approval. The Series B Preferred Shares have an initial conversion rate (the “Series B Conversion Rate”)
of 21.7378 shares of Common Stock per Series B Preferred Share, subject to customary anti-dilution adjustments. Holders of Series
B Preferred Shares have the right to elect to receive Series C Warrants in lieu of shares of Common Stock upon the mandatory conversion
of the Series B Preferred Shares to the extent such conversion would cause such holder to hold 10% or more of the Issuer’s Common
Stock. Based on the initial Series B Conversion Rate, approximately 18,590,057 shares of Common Stock would be issuable upon conversion
of all of the outstanding Series B Preferred Shares.

Except as required
by law or the Issuer’s Third Amended and Restated Certificate of Incorporation, as amended, holders of the Series B Preferred Shares
will have no voting rights, except for the right to consent to the Issuer’s creation, authorization or issuance of any class or
series of stock senior to the Series B Preferred Shares, other than the Series A Preferred Shares, (or any security convertible

B Preferred Shares (or any security convertible into stock on parity with the Series B Preferred Shares), and amendments to the
Issuer’s constituent documents that would adversely affect the rights, preferences, privileges or voting rights of the holders

Shares are outstanding, subject to certain exceptions, the Holders shall be entitled to receive, upon the conversion of the Series
B Preferred Shares into shares of Common Stock, the cash or other assets or property to which they would have been entitled had
the Series B Preferred Shares been converted on the record date for such dividend or distribution.

The

Certificate of Designations of Mandatorily Convertible Series B Preferred Stock set

Certificate of
Designations for the Series B Preferred Shares, dated as of January 29, 2018, a copy of which

Series
C Warrants

On the Settlement
Date, the Issuer issued 8,286,061 Series C Warrants in connection with the consummation of the 2018 Exchange Offer in a private
placement exempt from registration under the Securities Act.

Pursuant to the Warrant
Agreement, dated as of January 29, 2018 between the Issuer and Continental Stock Transfer & Trust Company, as Warrant Agent
(the “Warrant Agreement”), each Series C Warrant gives the holder thereof the right to purchase one share of Common Stock,
subject to certain exceptions, including receipt of shareholder approval and a limitation on the ability of certain holders to
exercise a Series C Warrant if it would cause such holder to beneficially own in excess of 9.99% of the outstanding Common Stock.
The Series C Warrants have an initial exercise price of $0.0001 per share of Common Stock, subject to customary anti-dilution provisions.
Upon a change of control or redemption of all of the outstanding Series A Preferred Shares by the Isssuer, the Issuer may cause
each Series C Warrant to be exercised, subject to certain exceptions (including receipt of shareholder approval), and limitations
(including a limitation on the ability of the Issuer to cause each Series C Warrant to be exercised if it would cause the holder
thereof to beneficially own in excess of 9.99% of the outstanding Common Stock).

Each beneficial
owner of a Series C Warrant shall be entitled to any dividend, whether payable in cash, in kind or other property, that would be
distributed to such beneficial owner if such beneficial owner’s Series C Warrants had been converted in full into shares of Common
Stock immediately prior to the close of business on the record date for the determination of the stockholders entitled to receive
such dividend.

The 812,321
newly issued shares (the “
New Common Shares”) of Common Stock, Series A Preferred Shares, Series B Preferred Shares
and Series C Warrants collectively represent 92.76% of the currently outstanding shares (approximately 131,292,475 shares) of Common
Stock, on a fully diluted basis as of the Settlement Date.

The
summary of the Warrant Agreement set forth above does not purport to be complete and is qualified in its entirety by reference
to the Warrant Agreement, dated as of January 29, 2018, a copy of which is being filed as Exhibit Y hereto and is incorporated
herein by reference.
