In 2007, women were also less well represented in physical ocean-

ography faculty positions (21%) than in other fields of oceanog-

raphy (31%) (Ranganathan et al., 2023). Nonetheless, the gender

ratios have improved in all subdisciplines and at all levels compared

to earlier data (Orcutt and Cetinić, 2014; O’Connell, 2014). For

non-faculty positions, data are less readily available, but globally,

the proportion of women ocean science researchers has increased

slightly from 38% to 39% from 2013 to 2020 (IOC-UNESCO,

2020). Women’s representation at leadership levels shows variable

improvement over the past few years—notably, three out of six US

oceanographic institutions were led by women in 2014,1 four out

of seven presidents of the American Geophysical Union (AGU)

Ocean Sciences section have been women since 2010,2 and five out

of 21 presidents of the American Meteorological Society (AMS)

have been women since 2004.3 The proportion of women co-chief

scientists of International Ocean Discovery Program (IODP)

expeditions was 32% between 2014 and 2018, and only two out

of 23 presidents of the International Association for the Physical

Sciences of the Oceans (IAPSO) have been women. According to

the 2019 annual report on the federal workforce published by the

US Equal Employment Opportunity Commission, only 25.9% of

all leaders in STEM are women (EEOC, 2019). This scarcity of

senior women creates dual challenges—those who achieve leader-

ship positions face isolation while bearing disproportionate men-

toring responsibilities for the next generation.

In 2005, under the leadership of Susan Lozier, 29 senior leaders

came together to collectively address the so-called “leaky pipeline”

of women in physical oceanography, whereby large fractions of

women trained in physical oceanography were not obtaining per-

manent positions in the field (Mackenzie, 2015). Several senior

leaders faced systemic barriers in their own careers while simulta-

neously needing to develop mentoring approaches without estab-

lished models. They hosted a workshop and conducted a com-

munity survey to assess mentorship needs of women in physical

oceanography (Lozier, 2006). Survey participants answered ques-

tions about their mentoring experiences, including when in their

career paths they obtained mentors, whether their mentors were

also their advisors, the genders of their mentors, and areas of

advice they received from their mentors. Lozier (2006) reported

that results of this survey highlighted differences between males

and females in relation to mentoring experiences: “All of the male

respondents had male mentors, while only 12% of the women

had female mentors. Twenty-four percent of the female respon-

dents said the gender of the mentor was important to them, while

none of the male respondents did.” Generally, female respondents

acquired mentors later in their careers than male respondents, typ-

ically finding mentors while in postdoctoral positions (Mackenzie,

2015). While many factors impact women’s career paths, it became

apparent that mentorship is one way forward for improvement

in gender equity because women, who were often geographi-

cally isolated from one another, lacked access to mentors and role

models. MPOWIR was established to address these mentoring

gaps, providing much-needed support for both early-career scien-

tists and their overburdened mentors. Within a decade of its incep-

tion, MPOWIR’s impact on mentees (late-stage graduate students

and early career professionals) was already notable (Clem et al.,

2014; Mouw et al., 2018).

The program serves as a powerful platform for professional

growth and career advancement. By cultivating mentoring rela-

tionships, MPOWIR provides invaluable opportunities for knowl-

edge transfer, career guidance, and emotional support—​benefits

that flow both ways. For senior leaders, it offers solutions to

long-standing challenges: lack of access to women mentors, geo-

graphic isolation, lack of resources, harassment, and care-​giving

responsibilities, among others (Figure 1). While mentees gain

access to seasoned perspectives, mentors report refined leadership

skills, including heightened awareness of systemic barriers and

stronger advocacy for equity in hiring and retention.

MPOWIR measures its success through longitudinal tracking

of participants’ appointments and broader field-wide trends. An

analysis conducted by Thompson et al. (2011) for physical ocean-

ography PhDs from six institutions from 1989 to 2009, showed

that whereas 25% of graduating men eventually obtained faculty

positions, the percentage of women PhDs obtaining faculty posi-

tions decreased from 23% in the first decade to 8% in the sec-

ond. Those who persisted to achieve senior roles often did so
