  <dc:description>&lt;p&gt;&lt;span&gt;Wave attenuation is a central process in the mechanics of a healthy salt marsh. Understanding how wave attenuation varies with vegetation and hydrodynamic conditions informs models of other marsh processes that are a function of wave energy (e.g. sediment transport) and allows for the incorporation of marshes into coastal protection plans. Here, we examine the evolution of wave height across a tidal salt marsh in San Francisco Bay. Instruments were deployed along a cross-shore transect, starting on the mudflat and crossing through zones dominated by&lt;i&gt;&lt;span&gt; Spartina&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;foliosa&lt;/span&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;Salicornia pacifica&lt;/i&gt;&lt;span&gt;. This dataset is the first to quantify wave attenuation for these vegetation species, which are abundant in the intertidal zone of California&amp;nbsp;estuaries. Measurements were collected in the summer and winter to assess seasonal variation in&lt;span&gt;&amp;nbsp;wave attenuation. Calculated drag coefficients of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;S.&amp;nbsp;foliosa&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;S.&amp;nbsp;pacifica&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;were similar, indicating equal amounts of vegetation would lead to similar&amp;nbsp;energy dissipation; however,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;S.&amp;nbsp;pacifica&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;has much greater biomass close to the bed (&amp;lt;20 cm) and retains biomass throughout the year, and therefore, it causes more total attenuation.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;S.&amp;nbsp;foliosa&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;dies back in the winter, and waves often grow across this section of the marsh. For both&lt;span&gt; vegetation types, &lt;/span&gt;attenuation was greatest for low water depths, when the vegetation was emergent. For both seasons, attenuation rates across&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;S.&amp;nbsp;pacifica&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;were the highest and were greater than published attenuation rates across similar (&lt;/span&gt;&lt;i&gt;Spartina alterniflora&lt;/i&gt;&lt;span&gt;) salt marshes for the comparable depths. These results can inform designs for marsh restorations and management plans in San Francisco Bay and other estuaries containing these species.&lt;/span&gt;&lt;/p&gt;</dc:description>
